small portable gold process plant

This arrangement and flowsheet of a Mini Portable Gold Processing Plant permits several mineral separations by flotation and provides for the possible recovery of other minerals by gravity concentration. The flowsheet is ideal for a pilot-plant in field testing of ores to determine the economic feasibility of an ore deposit prior to the installation of a larger plant or for processing ore during the development stages of a mining property.

The arrangement shown here features the economy type rubber-lined Grinding Mill. This mill is roller-mounted with V-belt drive around the mill shell, driven from motor-connected gear reducer. Material discharged from the grindingmill is sized through a spiral screen ahead of a Cyclone Classifier. The flotation cells handling initial feed are equipped with patented discharge cones for return and recovery of a heavy mineral fraction by a jig.Tailings from the flotation machines are fed to a #6 Concentrating Table to assure gravity recovery of any valuable mineral not amenable to flotation. Pan Filters are provided to de-water concentrates.

One of the most serious problems confronting the mining industry today is how to profitably begin the small scale milling of ores from mines where insufficient ore has been developed to warrant an expensive mill installation, but where a large plant might be needed later. The same question arises in connection with the economical working of numerous small but relatively high grade ore deposits.

Portable Mills, and in particular, Truck Mills, are a most practical solution to this problem. For a relatively small investment a complete and efficient mill can be brought to the mine and speedily put into operation. When the high grade deposit has been worked or the formerly promising operation no longer fulfills the operators expectations, the mill may be transported as a complete unit to another location.

In the Truck Mill the portability has been carried out to the highest degree. All of the units are carried on a truck or semi-trailer, which serves as the operating floor for most of the units. Power for the entire milling unit is usually supplied with either a Diesel or gasoline driven electric generating set, but a belt driven mill can be supplied.

gold wash plant for sale

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.

guide of alluvial gold mining process and alluvial gold equipment used in the alluvial gold washing plant - xinhai

The rock gold in the mountain is separated from the quartz vein caused by water erosion. Most of this kind of gold is fine as the sand, so it is called alluvial gold. but what are the alluvial gold mining processes? And what is alluvial gold equipment commonly used in the alluvial gold washing plant?

Due to the free state of gold in sand gold deposits, and the specific gravity difference between gold and sand is very obvious, the gravity separation method is an ideal and efficient method to extract gold from the sand.

The principle of the alluvial gold mining process is to recover gold and all kinds of associated heavy minerals from raw ore as much as possible by the gravity dressing method. The lower limit of the particle size of gold recovery by gravity separation method is generally 0.01mm. In the practice, the alluvial gold mining process generally includes breaking, screening and gravity separation.

Many gold ore deposits contain cementing mud masses, some of which have a particle size greater than 100mm, sometimes even cement on gravel or pebbles. If not broken in time in the alluvial gold washing plant, the mud will be discharged along with the waste rock during the screening process, resulting in the loss of gold.

The screening operation can remove 20-40% of the waste rock (gravel, pebble), which is an indispensable operation in the alluvial gold washing plant. The determination of screening parameters must be based on the size composition of gold in the original ore. According to the ore washability, the alluvial gold washing plant generally can use plane vibrating screen, cylinder screen, scrubbers with the screen, hydraulic washing equipment.

Due to the different size composition of the gold in the alluvial gold deposit, the effective particle size limits of the materials treated by various gravity separators are also different. In general, the alluvial gold equipment mostly adopts jig as the roughing equipment and the shake table as the concentrating equipment for the jig coarse concentrate. Some low-grade alluvial gold washing plant adopts the chute as roughing equipment, the jig as scavenging equipment and the shaker table as the concentrating equipment. Therefore, the reasonable alluvial gold mining process is mostly the joint operation of several kinds of gravity separators.

The jigging process is to mix the mineral particles with different specific gravity and stratify them according to the specific gravity in the variable speed medium flow with vertical movement. The minerals with small specific gravity are in the upper layer, while the minerals with large specific gravity are in the lower layer. The layered materials are discharged separately by means of machinery and water flow.

The jig used for gold recovery is suitable for separation of coarse mineral particles (any raw mineral materials except for superfine material mineral), the range of beneficiation size is from 50 mm to 0.074 mm. The lower limit of beneficiation size is 0.04 mm for the alluvial gold mining process if the proportion difference is equal to or larger than 1.25, and the ore achieves the monomer dissociation.

The shake table is a kind of gravity separator in the inclined medium flow. It uses the combined action of the specific gravity difference of sorted minerals, alternating movement of bed surface, and transverse oblique water flow and riffle (or notch groove) to allow loose layering of ores on the bed surface and fan-shaped zoning. Then different products can be produced.

The shaking table used for the alluvial gold mining process is suitable for processing the minerals with fine particles. According to the different particle sizes, the ore can be divided into a coarse sand bed, fine sand bed and slurry bed. The coarse sand bed is suitable for the material particle size between 2.0 mm to 0.5 mm, the fine sand bed is suitable for processing material particle size between 0.5 mm to 0.074 mm, the slurry bed is suitable for processing the material particle size between 0.074 mm to 0.037 mm.

The chute used in the alluvial gold washing plant is a kind of gravity separator relying on the inclined water flow. The material particles settle on the different zone of chute under the joint force of water flow, mineral gravity, frictions between mineral grain and chute bottom. The particles with a small proportion are taken away by the water flow, and the particles with a large proportion are left.

The chute is suitable for the treatment of the alluvial gold with low mud content. The particle size range is 0.6 mm-0.03mm. Gravity separation by chute used in the alluvial gold mining process is featured with simple structure, large processing capacity and low comprehensive cost.

In the production, the selection of alluvial gold mining process and alluvial gold equipment need to be determined according to the specific ore properties and characteristics. Not all the alluvial gold washing plants adopt the same alluvial gold mining process and alluvial gold equipment can obtain the ideal separation effect. It is suggested that the mineral processing test shall be carried out first, so as to develop reasonable alluvial gold mining process and tailor-made alluvial gold equipment.

gold project ore processing plant engineering design

The pouring of the first dore bar on April 21, 1983, marked the conclusion of an engineering and construction project which brought about the revival of mining in Mercur Canyon, 105 km (65 miles) southwest of Salt Lake City, Utah. Previous mining activity in the canyon had ceased at the beginning of World War II, when all gold mines were shut down. The Mercur Project was completed under budget and six weeks ahead of schedule.

a) Upgrading and modifying of the existing 11 km (7 miles) of Tooele County road, from State Highway 73 to the project area b) Site earthwork, including construction sediment dams, project area roads and initial mine haul roads c) Preproduction stripping of Mercur Hill-Lulu ore body d) Tailings disposal, including embankment, pipeline and recovery systems e) Offices, laboratory, shops, warehouse and security facilities f) Thirteen km (8 mile) water supply line and two 365-m (1200-ft) deep water wells.

In order to meet both objectives, initial discussions centered on the plot plan and the best location for the facilities, including consideration of the possible need for an oxidation circuit and future expansion requirements. The approximate sizes of the major process areas were developed and cutouts made to match the scale of a topographic map of the area.

The engineering design schedule for the project required a multiple task approach with design activities underway on several areas at the same time. Communication between each activity was maintained by establishing a project area where all major activities took place. Frequent design development meetings were held so that representatives of all aspects of the project could provide input.

The initial flowsheet contained several areas which required further definition. Test work was underway to determine the residence time required for CIL and a study was conducted on the need for pressure oxidation. While this work was going on, specifications for the major process equipment in the comminution circuit were being written. Several alternative layouts were developed for the mills and mill drives. In order to quickly establish the optimum configuration of the mills, a styrofoam model was constructed representing the mills, cyclone feed sump, cyclones, screens and pumps.

The requirements of the short construction schedule also impacted the detail engineering phase of the project. In order to get concrete and steel drawings to the field in a timely manner, it was necessary to begin design of the major equipment and structure foundations and structural steel before the process was finalized. The small amount of engineering time lost with changes was more than made up for by the availability of drawings for construction. The need for completed foundations at an early date also placed emphasis on vendor expediting for the required information. An automatic system of expediting vendor drawings was initiated to keep the project informed of the key dates in this area. Particular emphasis was placed on the equipment that required engineering interface for foundation, piping or electrical design.

In addition to the process facilities, the project includes a mine services building which houses a truck shop, mining engineering and geological offices, and a machine shop and maintenance area. Due to the severe space restrictions on the site, all of these facilities were combined into a single unit located so that the mine haul trucks could access the building without entering the process area and so that the process maintenance facility could be near the major process facilities. In addition to the mine services building, a laboratory building, administration building and gatehouse were provided.

Other ancillary facilities included water supply facilities, electrical distribution and a tailings pond embankment. The 79-m (260-ft) high tailings pond embankment design required extensive field work, which was accomplished during the fall of 1981. With this work completed, the design and permitting process inherent in a structure of this type was completed over the winter and the field construction began in the following spring.

These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost-efficient process designs.

Based on abundant experiences on gold mining project, Prominer helps clients to get higher yield & recovery rate with lower running cost and pays more attention on environmental protection. Prominer supplies customized solution for different types of gold ore. General processing technologies for gold ore are summarized as below:

For alluvial gold, also called sand gold, gravel gold, placer gold or river gold, gravity separation is suitable. This type of gold contains mainly free gold blended with the sand. Under this circumstance, the technology is to wash away the mud and sieve out the big size stone first with the trommel screen, and then using centrifugal concentrator, shaking table as well as gold carpet to separate the free gold from the stone sands.

CIL is mainly for processing the oxide type gold ore if the recovery rate is not high or much gold is still left by using otation and/ or gravity circuits. Slurry, containing uncovered gold from primary circuits, is pumped directly to the thickener to adjust the slurry density. Then it is pumped to leaching plant and dissolved in aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed directly into coarse granules of activated carbon, and it is called Carbon-In-Leaching process (CIL).

Heap leaching is always the first choice to process low grade ore easy to leaching. Based on the leaching test, the gold ore will be crushed to the determined particle size and then sent to the dump area. If the content of clay and solid is high, to improve the leaching efficiency, the agglomeration shall be considered. By using the cement, lime and cyanide solution, the small particles would be stuck to big lumps. It makes the cyanide solution much easier penetrating and heap more stable. After sufficient leaching, the pregnant solution will be pumped to the carbon adsorption column for catching the free gold. The barren liquid will be pumped to the cyanide solution pond for recycle usage.

The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated onto cathodes of steel wool. The loaded steel wool is pretreated by calcination before mixing with uxes and melting. Finally, the melt is poured into a cascade of molds where gold is separated from the slag to gold bullion.

1. Mercury amalgamation-gravity separation This process involves gravity separation and then mercury amalgamation or mercury amalgamation before gravity separation. The former method is mostly used for the placer gold which with low gold content, or the surface contaminated ore. The latter is mostly used for the quartz vein gold-bearing sulfide ore. 2. Gravity separation (amalgamation)-cyanide process This gold processing method is suited for the quartz vein type gold-bearing oxidized ore which with uneven disseminated grain size and high oxidation degree, the gold-bearing ore basically free of copper, arsenic, antimony, etc. 3. Flotation process This processing method is suitable for the quartz vein gold-bearing ore, gold-bearing altered rock type ore and sulfides ore which with fine gold particle and good floatability, widely applied in the medium-large good mining plant. 4. Gravity separation (amalgamation)-flotation process This procedure is applicable to the uneven disseminated grain size and low sulfur quartz veins containing gold ore. Since the monomer-dissociated gold is recovered in a timely and early manner in the grinding circuit, the total recovery of gold can be increased. This process is a widely used process in China's gold plant, in which the recovery rate of gold can reach 30-60%. 5. Cyanidation (full mud cyanidation) process Applicable to gold with a higher emerald grain size, a deeper iron ore-bearing pyrite quartz vein type ore, or a gold-altered diorite-type ore. The ore is required to contain no elements harmful to cyanidation such as copper, arsenic or antimony. 6. Flotation-Cyanide Process This process is suitable for the treatment of gold-bearing iron ore quartz vein ore with gold and sulfide symbiosis. It is also suitable for gold-bearing granite fracture zone altered rock type ore, especially for high sulfur ore. To apply. This process is also one of the common processes in China's gold mines. 7. Flotation-baking-cyanide combined process This procedure is applicable to gold-bearing quartz vein type ores containing elements such as arsenic and antimony. The roasting process is a preparation for cyanidation in order to remove elements that are harmful to cyanidation.
