Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant. The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate. When the mined gravel is fed into the washplant. It is classified by particle size using various stationary or vibrating screens. Classifying gravels provides for more efficient gold recovery, reduced water consumption, and facilitation of mine site rehabilitation, and is practiced by most operators. The oversize material, usually larger than two inches, slides out of the washplant into a pile where it can be moved by a front-end loader or bulldozer. The undersize material and gold-bearing gravel is mixed with water and flows through the sluicebox where the gold and heavy black sands are concentrated. Tailings are gravel, sand, and other materials accumulated at the end of the sluicebox. Tailings are routinely moved away from the sluicebox by a loader or bulldozer.
The water that carries the gold-bearing gravel through the sluicebox becomes sediment-laden and turbid. This muddy process water flows from the end of the sluicebox over a pile of fresh tailings into a series of settling ponds. These ponds are designed to hold the muddy water long enough for the fine sediments to settle. The physical design of the ponds depends upon the amount of water flowing through the system, the sediment characteristics of the gravels being worked, and the physical characteristics of the site. Most mines use a series of small settling ponds to permit more flexible water management. Small ponds are usually easier to build, repair, dean, replace, bypass, and rehabilitate than larger ponds. The use of pre-settling ponds is encouraged. A pre-settling pond is located in the tail race between the sluice and the first settling pond. Sands and other heavy settleable solids are collected here where they are easy to wash.
However, some zero-discharge systems do have occasional discharges, usually due to water seepage through pond dikes. This seepage almost always meets the settleable solids effluent standards, and in most cases, Is probably of better quality than the water discharged from typically operated settling ponds. I.e., less settleable solids and lower turbidity. Carefully designed and Implemented water management practices are required to achieve zero discharge of muddy water into adjacent streams. Water used in the sluicing process Is pumped from the nearby stream through the washplant and into the settling ponds. Water Intake from the stream Is suspended when the ponds contain adequate water to support continued sluicing operations by recycling pond water to the washplant. In some cases, groundwater seepage Into the settling ponds may be sufficient to eliminate the need for adding stream water to the system. The practice of zero discharge and the recycling of mine water contributes to compliance with federal effluent limitations and State water quality standards.
Placer mining involves equipment ranging from a simple gold pan all the way up to trucks, excavators, and a gold wash plant.This type of gold prospecting usually involves less investment and will consistently yield small amounts of gold, with occasional bonanzas for those who are persistent. If you can learn to reliably return from every trip with decent concentrates, so that over time you fill a five-gallon bucket, and then maybe even a fifty-five-gallon drum, with black sands, magnetite, ilmenite, rare earth elements (REEs), and gold, you will be rewarded in the long run.
Either way, your long-term goals are your own.Very few prospectors are simply in it for the money, looking at this as a way to become a millionaire overnight. Some of us just like to get out of town, camp in the mountains, and enjoy the spirit of the outdoors. Some people like to work up a little sweat and appetite, improve their health, and learn a little. Some of us like to solve problems and run machinery, and enjoy the challenge of keeping a pump going or making sure the sluice is running right. Still others like the wildlife, the scenery, and the historical importance of the Wild West, and bring back their riches as photos and videos. In each case, if you toss in a little gold fever as motivation and stay scientific about your sampling and exploration, you will prosper far and above the value of your recovered material.
Still, a nice payday is always a treat. One sure way to reach that goal is to keep trying. Keep practicing, keep exploring, and keep getting out in the field. Another truism that seems to hold is that the farther away from civilization you get. the better your chances.
The development of a load/placer mine and the selection of the proper gravity recovery plant is more difficult than most people realize. Television shows have glamorized mining making it look like anybody can start a mine with little to no experience. What people dont realize is that mining is a structured engineering discipline taught at university. Just as you should not build your own bridge without knowledge of civil engineering, you should not think becoming a miner is a simple task. If you have no experience in the mining field you need to get educated about the process before you embark on this adventure. We have compiled a basic guide to assist in that process.
The terminology used for this type of mining is often interchanged. The term for the type of deposit under consideration is alluvial. Alluvial deposits are formed when the gold has migrated from its original deposition by weathering to a new location often inactive stream beds or in historic watercourses now overlain by sediments or glacial sediments.
In general Placer Mining is typically the recovery of gold from stream sediments through the use of dredges and sluices or other gravity means. Load mining generally involves the stripping of an overburden layer (soil) to uncover the underlying gravels that contain the gold. These deposits are often mined with mobile equipment and the ore trucked to a gravity treatment plant.
1. Permitting am I allowed to disturb the land excavating pits, leaving tailings behind, water usage, noise, air quality. In most cases you are not allowed to simply start mining even on your own land without the proper permits.
2. Resource estimation how much gold is present (grade and tonnage) and what does the deposit look like over burden depth, ore depth, gravel size. Generally, a placer resource is established by drilling or augering holes around the deposit to delineate the extent of the gold. This is often combined with field gravity recovery testing to provide an estimate of the recoverable grade.
6. Mine plan do you have a mine plan where are you going to mine first, where is the overburden going to be placed, where are the tailings going to be placed, is the plant going to be in one spot or moved during the mine life, what are the haulage distances. Is this a seasonal operation?
Mine Conditions Where is your project located? terrain, climate, infrastructure variables How large is your concession? Is a mobile or fixed plant right for this application? How many yards/hour (m/hr or tons per hour) do you want to process? How much water do you have available (GPM or m/hr)? Is there power available from the grid or do you required generation?
Plant Characteristics Are you looking for a mobile machine that you move regularly or a stationary plant that you haul your ore to? What type/size of equipment will you be feeding the plant with (front end loader, dredge pump, other)?
Feed Characteristics Ore consistency: What is the estimated maximum boulder size (in, mm)? Is there significant clay present? What is your maximum gold size (mm or um)? Is there fine gold present, what is the typical size (um)?
8. Economic Model Once you have made some initial assumptions you need to develop an economic model (even a basic one) so that you know if the project is viable before you start. No matter what type of project you should try and establish some basic economics unless this is just going to be a small hobby operation where profit does not matter. There are a lot of assumptions required to develop the model and you need to be realistic in your assessment. Add contingencies for operating costs of 10-15% and 20-30% for capital costs.
The IGR 100 Modular Small Scale One Man Gold Wash Plant is a self-contained fine gold recovery equipment system. It uses classification and enhanced gravity to assure you are catching the finest gold and the big nuggets. In the standard configuration material flows as follows:
Capacity: 2 tons per hour passing the screen to the concentrator The feed to the screen will be greater depending on the size distribution of your material Electrical Requirement: 8kW 220Volt Generator, Single Phase Water Consumption: 50 mm external pump is suggested (not included)
All components in this Gold Processing Plant are matched in capacity and transportable in the field. Each item comes with a Variable Frequency Drive (VFD). These allow the use to easily adjust each item to their needs. The VFDs also allow operation from different types of power supplies used around the world. VFDs are rainproof and suitable for outdoor service. All components are designed to connect to a standard 220 Volt, 1 phase gasoline powered generator.
The large barb on the left hand side is the clean water connection. Connect this to a pump capable of supplying both the clean process water near 15 L/M and the slurry water near 77 L/m (to make 30% solids at 2 tph) at 15 psi.
Using the small diameter hose supplied () connect 2 valves to the matched size barbs on the screen. During operation the valves on the water distribution manifold will be used to regulate the water to the spray bars on the screen. Open the valves sufficiently for the spray to fan across the full width of the screen.
The important thing to note is that the iCON components all use 3phase 220 volts. The user only needs to supply 1phase 220 volts. The VFDs provided clean/regulate the power, control the frequency and convert 1 phase voltage to 3 phase.
Supply lines from the customers source (outlet or generator) to the distribution box (grey box mounted on the upper left of the stand) and from the distribution box to the VFDs require only 3 conductors: 2 lines and ground.
Using the supplied 3 conductor wire, cut 3 lengths to fit from the distribution box to each of the VFDs. These lengths will be approximately 1.5 to 3 feet. Use the remaining 3 conductor wire to connect the user supply to the distribution box.
Inside of the distribution box join the 4 green wires together using wire nuts or electrical tape. The green wires can be attached to the steel frame if desired. Join each of the other matching colors together using either wire nuts or electrical tape.
Join the 3 conductor supply wires inside of each VFD. Use caution to insure that no wires accidently touch another. The green wires attach to the ground prong just as the existing green wire is attached.
After confirming functionality without the electrical plugs, one can install them taking note of the instruction on the plastic packages. The most important thing is assure that the green/ground wires connect from the plug to the socket. The terminals are colored green to help assure this is done correctly. The arrangement of the other 3 wires is up to the user. It the equipment rotates in the wrong direction simply swap any 2 of 3 wires as described below.
On the pump, press the green start button and use the arrow to set the hertz to 10. As you look down on the pump, it must rotate clockwise. This means the slurry will be thrown in the direction of the pump outlet. If rotation is not correct, simply swap the connection for any 2 of the 3 wires from the VFD to the pump motor. The pump is limited to 70 hertz. Do not operate the pump for any longer than required to verify the rotation without water.
Test the Gold Processing concentrator be pressing the green button and using the arrow to rotate at 10 hertz. The direction of rotation is not important. The pump is limited to 50 hertz from the factory. Do not operate for longer than required to verify functionality without water supplied to the fluid coupling. The concentrator may squeak initially and may have the odor of warm rubber. This is not a concern as there is an o-ring that must be broken-in.
On the Gold Processing screen, press the green button on the VFD to start vibration. Use the arrows to increase the vibration to it maximum. Test a small amount of sand on the screen. If the wet material seems to bounce down hill, then change the rotation of the motor by swapping any 2 of the 3 wires from the VFD to the screen.
The screen is designed to classify the material in 2 size fractions. The sand finer than 2 mm will pass through the screen and will be pumped to the concentrator. Therefore, the outlet of the screen must feed into the pump. The vertical height can be arranged using the shipping pallets if desired.
The sluice attaches to the tails outlet of the concentrator. The sluice is not intended to catch fine gold. The sluice used the volume of water from the concentrator tails to carry the material over the riffles.
The screen must be located with the finger grizzly above the sluice. At material too large to pass through the screen reaches the grizzly, the material finer than 6mm will fall through the grizzly and to the sluice intended only as a nugget trap. Any material bigger than 6mm and therefore passing over the finger grizzly will be rejected by the system.
i150 has a Invertek VFD which is a single phase drive with 200-240/1/50-60Hz Single phase input and 230/3/60Hz 3 phase output. The motor is a 3 phase motor 208-230/3/60Hz which has to wire to the output of the VFD.

They are economical withhighest and fastest return of investment. With over 5 decades in fabrication, DOVE Portable Gold Wash Plants were supplied in every country in Africa and South-East Asia, Columbia, Brazil, and Guyana.
These crucial steps are achieved by different machine components in a Portable Gold Wash Plant configuration. Any short cut of the crucial steps shall result in lack or reduction of recovery of the Gold Production or loss of the Gold Production.
Gravity separation, or Gravity Concentration, is one of the oldest proven recovery methods in the history of gold mining. It has been tested and approved as a technique of concentration of free flowing gold and has been used as a primary system for concentration and recovery of gold.
The Gravity separation method consists in separating minerals or metals from one another using their difference in specific gravity and of their relative response to other forces they are subjected to.
In Portable Gold Wash Plant, using Gravity Separation process, the gold particles are subjected to forces in a medium, such as water. The response of the gold particles to these forces shall enhanced resistance or accelerated settling time, depending on their specific gravity, which will allow for the separation to occur. In this way, gold particles with specific gravity of (S. G. 19.32) and the gangue can be separated from one another due to their difference in specific gravity and response to the various forces in the water.
By using Gravity Separation, DOVE Portable Gold Wash Plants reduce the costs involved in crushing and grinding of the material, and also reduce the slime losses that usually result from unnecessary and abusive size reduction operations.
In a DOVE Portable Gold Wash Plant, every component is crucial for efficient operations and proper processing the Gold Ore, which are important to achieve high recovery of the Gold Production. DOVEs unique designs are embedded in each of the Portable Gold Wash Plants components to insure the efficient recovery of 100% of the Gold Production, with no loss of production.
is a large hopper designed to feed the Ore to the rest of the wash plant. This hopper can be a wet or dry type depending on the projects requirements. The hopper is designed to be fed with earth moving equipment, such as conveyors, gravel pumps, Excavators, Loaders or Dump Truck, with respect to the plant capacity (Tons Per Hour) solids.
DOVE Ore Feed Hoppersare supplied in different capacities, and specifications, designed and engineered as interconnecting components for easy and rapid assembly, installation and rapid disassembly at mining site.
DOVE Ore Feed Hoppersare fabricated with heavy cage of steel plates of 5-12 mm, to insure their durability and to stand severe conditions of the mining site. Additionally, they are designed to be easily connected to high-pressure Hydraulic spray-Jets system, Hydraulic Manifold and piping system. Their slurry outlet is configured in different sizes for ease of connection to the Static or Vibrating Grizzly.
is a powerful Canon that produces high pressure water Jet Spray, used to break the clay contain of the Ore at early stage of feeding, as well as assist in speedy ore throughput. The canons are highly effective in wet ore feeding system and when the ore has high clay content. They assist with the logistics of the Ore, in the form of Slurry, into the Ore Feed Channels and to the next step of operation.
DOVE Monitorsare casted in hardened steel (high carbon) and have a bronze or hardened steel head. They are supplied with an Operator Cabin Stand Structure, designed for long hours of operations under extreme weather conditions. DOVE Monitors are rugged and designed to operate using recycled water in the mining site.

These unique andunparalleled features make DOVE Wash Plants the number one desired solution for every mining company.
Screening is the process of separating the material according to their size by simply passing it through a screen or various sizes of screens, which can be vibrating or static. Screening can be done in multiple stages to achieve higher efficiency.
are screens of various sizes used for the first screening stage in DOVE Portable Gold Wash Plants. Grizzly Separators are designed to screen the large oversized rock particles from the ore, prior to the next stage of ore transportation, through slurry channels (wet feed) or belt conveyors (dry feed), and classification. The screen mesh sizes are chosen in accordance with the ore characteristics and project specifications.
This component is important, since it rapidly eliminates the large unwanted rocks to avoid them going to the classification and concentration stages. This means that only the mineral bearing ore is processed throughout the next stages of the wash plant, hence, reducing the amount of material that needs to be processed.
DOVE Grizzly Separators are configured with High Pressure Spray Jet Module and complete Hydraulic Network, designed to break the clay sticking to the rock particles and eliminate the risk of losing the precious minerals that might stick to the oversized rocks due to the clay.
A Trommel Classifier is large revolving cylindrical screens installed on a supporting base, in a slightly inclined position. Trommel is powered by electric motor or diesel engine, or in some cases by hydraulic power. The Trommels cylindrical screen spins in order to sort through the material that is being introduced through its feeding end.
The Trommel is a major component of a Portable Wash plant, designed to perform classification of the ore, as well as breaking valuable minerals free from the host clay. Once freed from the host clay, the materials are also classified according to their sizes, reducing the volume of material that will be processed in the next stages for increased efficiency of the recovery process.
All DOVE Multi-Stage Classification Trommels are offered with Trommel Feed Hopper, Hopper Hydraulic Clay Breaking Network, Security Covers, 3-way Engine/Motor Security Canopy and Locking Mechanism, High Pressure Main Hydraulic Spray Jet System, Clay Breaking Module or Scrubber Module, Diesel Engine or Electric Motor, Geared Speed Reduction, Wheel Set Trailer, Hitch Mechanism, Undersize Rubber Lined Feed Channel, Feed Channel Rubber Lined for Coarse Material, Water Manifold and Hydraulic Piping Network, and Height Adjustment Mechanism and optional Conveyor assembly for reject.
Jig Concentrators are Gravity Concentration devices designed and mainly used in mineral processing for washing, separation and concentration of coarse metals & minerals within theore, based on their specific gravity. These concentrators subject the particles within the ore to a jigging motion in the medium of water, which accelerates their settling time with respect to their specific gravity, while separating them over a selected screen mesh size.
Since the high specific gravity differential of material makes recovery possible, the use ofJig Concentratorsto recover various metals and minerals is wide within the mining industry.Jig Concentratorsunique ability to absorb fluctuations in ore grades, tonnage rates and dilution, without any effect on recovery results, makes them the most important and essential devices in mineral recovery.
DOVE Jigsare designed with unique features, which are unparalleled in the industry. You will find DOVE Jigs in practically every country on the African Continent, in South East Asia, in Brazil, in Colombia and in Guyana.

They are used for the recovery of fine particles of free gold for mining projects that do not used cyanide or other toxic chemicals due to environmental concerns, government regulations or the high cost of cyanide and other toxic chemicals for gold recovery process.
DOVE Gold Centrifugal Concentratorshasadvanced features and design. DOVE Gold Centrifugal Concentrators utilize G-Force to efficiently recover fine gold particles by enhancing the gravitational force to optimize separation capabilities.
DOVE Gold Concentrators are supplied with security system and locking mechanism, complete hydraulic system and high pressure multi-stage water pumps, ore feed module including slurry pump and sump tank for feed monitoring, hydrocyclone and rubber fish tail as concentrate moisture adjustment mechanism and to control solid flow.
Gold Concentrating Tables are known as one of the most effective and selective machines for wet Gravity Separation. They have the unique ability to separate minerals with fairly close specific gravity values from each other, which is nearly impossible to achieve with other equipment designed for wet Gravity Separation.
DOVE Gold Concentrating Tablesare comprised of wooden decks with ultra-smooth rubber cover and riffle surface and are operating in horizontal plane, where material with higher specific gravity is separated from material with lower specific gravity.
Head Motion imparts a reciprocating movement to the tables deck in a horizontal plane. As the material moves across the table, the shaking action of the deck causes size classification and specific gravity stratification.
The flow of cross water causes shearing of stratified material and forces it to cascade over the riffle surface of the tables deck. Lower specific gravity material remains close to the water surface and rides over the riffles towards discharge end of the table; higher specific gravity material is being hold back by the riffles, which is closest to the tables surface, and moving along the tables deck to the concentrate discharge.
Smelting is the process of refining an ore. The ore is subjected to high temperatures that will melt it, resulting in a chemical change of the ore that allows for the metals to be converted into a purer form.
In the Portable Gold Wash Plant, the Smelting Furnace is used after the Gold Concentrating Table, to remove the unwanted impurities while melting the Gold. The result will be a melted gold and a slag that are separated from each other due to their difference in melting point and density. The slag can easily be removed and the melted gold will be molded into Gold Dore Bars.
DOVE Smelting Furnace is supplied with Hard Burned Crucibles where the material can be safely melted at high temperature, Quartz Rods to stir the melted alloy, Tongs to safely garb crucibles over the high temperature in the furnace, Sliding Ingot Mold for the creation of Gold Dore Bars, and Stamping Tools to mark the dore bars with the desired initials and serial numbers.

Next, the screen deck further classifies the material, and sub-.25 (6.35 mm) material drops into the sluice boxes, remaining sub-1 material passes through the nugget trap into the final riffle set for capture, and larger rocks get discarded.The sluicing system has three boxes that are independently adjustable, and with anywhere from 20 feet of sluice box on our 50-ton units to 40 feet of wider boxes on the 200-ton units, gold recovery is excellent. It often exceeds 95%, even with fine gold down to 200 mesh! Whats the key to such remarkable recovery? Science.

Portable wash plants are also known as Portable Alluvial Wash Plants, Portable Placer Wash Plants, Portable Alluvial Processing Plants, Portable Placer Processing Plants or Portable Trommel Wash Plants.
Different machines that are configured as components of the Portable Wash Plant will achieve these crucial steps. Skipping any of the crucial steps will result in lack of recovery or loss of the valuable minerals.
Gravity separation, also known as Gravity Concentration, is one of the oldest recovery methods in the mining and has been used as a primary form of mineral concentration for centuries. Gravity separation has been tested and approved as one of the best techniques for the concentration of free flowing minerals.
In a Gravity Separation process, the metals and minerals are subjected to forces in a medium, such as water, air, or other heavy medium. The response of the minerals and metals to these forces can be enhanced resistance or settling velocity, depending on their specific gravity, which will allow for the separation to occur. This way, valuable minerals and the gangue can be separated from one another due to their difference in specific gravity and response to the various forces in the medium.
By using Gravity Separation, DOVE Portable Wash Plants eliminate the costs involved in crushing and grinding of the material, and also reduce the slime losses that usually result from unnecessary and abusive size reduction operations.
In a DOVE Portable Wash Plant, every component is crucial for the efficient operation of the Wash Plant and proper processing the ore and high recovery of Gold, Diamonds and other minerals production. DOVEs unique designs are embedded in each of the Portable Wash Plants components to insure the efficient recovery of 100% of the Gold Production, with no loss.

Screening is the action of separating the materials according to their size by simply passing them through a screen or a number of screens, which can be in motion or static. Screening can be done in multiple stages to achieve higher efficiency.
come in various sizes and are used for the first screening stage of DOVE Portable Wash Plants. Grizzly Separators are designed to screen the large oversized rock particles from the ore, prior to being transported, through slurry channels (wet feed) or belt conveyors (dry feed), to the next stage of classification. The screen mesh sizes are specifically chosen according to the ore characteristics and project specifications.
The rapid elimination of the large unwanted rocks by the Grizzly Separators an essential step, which will prevent the large rocks from going to the Classification and concentration stages. This means that only the mineral baring ore is processed throughout the next stages of the Portable wash plant, hence, reducing the amount of material that needs to be processed and eliminating damages that could be caused by the rocks on the long run.
Configured with High Pressure Spray Jet module and complete Hydraulic Net work, DOVE Grizzly Separators are designed to break the clay sticking to the rock particles. This eliminates the risk of losing the precious minerals that might stick to the oversized rocks due to the clay.
is, essentially, a large cylindrical screen, installed on a supporting base in a slightly inclined position, which spins in order to classify the material that is being introduced through its feeding end.
The Trommel is designed to perform classification of the ore, as well as breaking valuable minerals free from the host clay and is a major component of a Portable Wash plant. After being freed from the host clay, the materials are classified according to their size, hence reducing the volume of material that will be processed in the next stages and increasing the recovery process efficiency.

Concentrating Tables are agreed by all to be the most effective and selective machines for wet Gravity Separation. They are used to effectively separate minerals from one another, even when each minerals specific gravity is close in value to that of others in the ore.
DOVE Concentrating Tables are composed of wooden or aluminum decks, that can have either have a rectangular or diagonal shape, with ultra-smooth rubber cover and riffle surface or are operating in horizontal plane, where material with higher specific gravity is separated from material with lower specific gravity.
The Head Motion applies a reciprocating movement to the tables deck in a horizontal plane and as the material moves across the table, the shaking motion of the deck causes size classification and specific gravity stratification.
The flow of water crossing the deck causes shear in the stratified material and forces it to stream over the rifle surface of the tables deck. The material of lower specific gravity continues to float near the water surface and spills over the riffles, towards discharge end of the table. Material higher specific gravity is held back by the riffles, near to the tables surface, and moves along the tables deck to the concentrate discharge.
