gold crushing - jxsc machine

What is the gold crushing process flow? how to extract gold from its ore? In the paper, I make details from the gold crushing circuit, crushing equipment, primary crusher, secondary crusher and tertiary crusher, screening. Join us.

Every gram of gold from the stones is indispensable to experience mining crushing grinding sorting smelting casting, etc., from the perspective of mineral processing, the crushing is the first mineral beneficiation process step, and it is almost a preparatory section for any gold processing plant. By crushing process, reduce the large ore to ideal particle size for grinding.

The gold crushing process design is determined by the ore amount, hardness and the crushing ratio. The most commonly used rock crushers are jaw crushers and cone crushers; in addition, vibrating screens (round vibrating screens) are required to complete the closed circuit with the crushers.

Jaw crusher is generally used as the primary crusher in the crushing circuit and connects to the ore feeding machine. In the early years, common used plate feeder, but now, the vibrating feeder is more popular. Practice has proved that the vibrating feeder has advantages of low power consumption, strong transportation capacity, low failure rate and easy maintenance, which can fully meet the needs of both of large scale gold plant ore small scale processing plant.

For medium hardness ore, the ore can be gradually crushed from the crusher mouth. For the ore with higher hardness, the material may be broken in the middle of the jaw plate, so that the opening width of the crusher mouth needs to be wider.

Each crusher has a maximum feed size, which surely is not a fixed value. For medium hardness ore, adopt extrusion type feeding mode, even if there is a small amount of large ore exceeding the maximum feed size, has no effect on the work of the crusher. On the contrary, if the material is high hardness ore, it is better to intermittently feed to avoid clogging.

In addition to the maximum feed size, an important parameter of the crusher is the discharge gap. The discharge gap is not equal to the maximum discharge size. The maximum discharge size of the jaw crusher is usually 1.5-1.8 times of the discharge gap. Each crusher has a minimum discharge clearance. In order to ensure the stability of the crushing process, 1.5-2 times the minimum clearance is selected to complete the first stage of the fracture.

The iron is fatal to the cone crusher, so the ore must be removed before enters the cone breaks. An iron remover (in fact, a magnet) can be added to the upper part of the belt conveyor to preclude the wire, nails, welding heads and the like.

For the cone crusher, it is must use the extrusion feeding method, intermittent feeding method damages the equipment very much. Therefore, professional cone crusher manufacturers will configure a small buffer tank for the cone crusher. The material from the fine crushing bin can be fed into the buffer tank through a belt feeder or a small vibrating feeder. If use a chute, you can remove the buffer and let the material accumulate directly in the chute.

Similarly, the cone crusher also has the maximum feed size. This parameter value is a mandatory parameter. Never try to exceed it. Once it is stuck due to excessive material, it is very troublesome for the cone crusher.

It should be noted that, due to the closed-circuit crushing formed by the vibrating screen, the cone crusher is not the larger the discharge gap, larger the processing capacity. Different discharge gap determine the different qualified product rates and the ore recrushing rates.

As the gap increases, the actual processing capacity of the crusher increases, the gap becomes smaller, and the speed of the crushing decreases. Both of these two conditions are harmful in production. We should find the best gap in the commissioning to make the production smoother.

As the vertebral body wears, the gap will increase accordingly. In addition, the maximum discharge size of the cone crusher will reach 2-3 times of the discharge gap, so the gap size can be judged according to the granularity of the discharge during the adjustment. Never blindly adjust without a clue.

Screen layer Generally speaking, small scale gold plant use single-layer screen, medium and large mines use double-layer screen, but the purpose of double-layer screens is not to grade three products, but to improve screening efficiency.

Material As for the choice of materials for the screen, it depends on the users usage habits. It is certain that the polyurethane (rubber) screen has a longer service life, a lower screening efficiency, and a steel-wire mesh that is more fragile, but has a higher screening efficiency and is easier to maintain.

Due to the relatively harsh environment of the crushing operation, the single shift time is less than 6 hours. Therefore, when selecting the gold crushing machine, the working time is generally determined by two shifts of 6 hours or three shifts of 5 hours.

Throughout the centuries, gold has been recovered from its ores in many ways. These range from the rocker or long tom of the California Forty-Niner and the noisy stamp mill of the 19th century to modern methods of leaching with cyanide. Any method of treating gold ores must take advantage of the natural characteristics of the metal. Cyanide solution, unlike most other liquids, is able to dissolve gold, and thus, is used in the processing of gold ore. When in solution (and in the presence of oxygen), cyanide slowly attacks fine particles of gold and ultimately dissolves them. It is strange, but fortunate (because cyanide is extremely toxic), that a weak cyanide solution attacks the gold particles faster than a strong solutions.

For the cyanide to attack the gold particles, it is necessary that the gold first be liberated from the worthless gangue rock which surrounds it because cyanide will not attack or dissolve most other minerals. Overall, the cyanide process is very efficient. A gold ore containing less than one gram of gold per ton can, in some cases (and depending on the gold price), be profitably treated. A modern cyanide mill recovers or extracts 95% to 98% of the gold in the ore. In a cyanide mill, lime and cyanide are added to the ore pulp in the grinding circuit. The lime has several functions: it protects the cyanide from being destroyed by naturally occurring chemicals called cyanicides and improves the settlement rate of the pulp in the thickening stage. Cyanidation (the actual dissolution of the gold) begins in the grinding step. Cyanide and lime solutions are introduced here, where newly liberated gold particles are constantly being polished by the grinding action and the solutions are heated by the friction. Depending on the ore and fineness of grind, from 30% to 70% of the gold may be dissolved during the grinding process. Additional time is required to place the balance of the liberated gold into solution. This is done by pumping the gold-bearing pulp to a number of mixing tanks, known as agitators.

Here the pulp is aerated either mechanically or by compressed air, or by a combination of both, for a predetermined period of time. This varies any where from 24 to 48 hours. The 1980s saw a rapid expansion in gold production from low-grade oxide deposits around the world. That expansion could not have occurred without the development of a new, low-cost method of recovering the gold. That process is called heap leaching. Heap leaching avoids most of the above steps, and does not even require that a mill be built, making it a very low-cost method of processing ore. Here, broken ore is heaped onto a thick polyethylene sheet, called a liner, and then dilute cyanide solution is sprinkled on top of the heap. As the solution trickles down through the ore, the gold is dissolved. Before the heap is constructed, the polyethylene liner is laid down in such a way that the cyanide solution will drain to a central point. From here the gold-laden solution is channeled into a man-made pond. One downside of heap leaching is lower recovery just 65% to 85% of the gold in the ore ends up in the gold bars a heap-leach mine produces. Extracting Gold Out of Solution: Traditionally, recovering the gold from the cyanide solution was achieved by separating the gold-laden, or pregnant, solution from the barren solids present and then precipitating the gold. The traditional approach is called the Merrill-Crowe method. The first step is to move the pulp from the agitators to one or more thickeners large, shallow tanks. The solution flows over the top of the tank and is collected in a launder around the tanks perimeter, while the worthless rock particle sink to the bottom and are slowly raked to the center by mechanical arms which operate continuously. The material is discharged through a pipe at the bottom of the tank but it contains too much valuable material to be discarded, so is filtered to recover additional gold.

Prospecting for gold can be a fun hobby, though its a lot of work! You may be able to harvest gold flakes from rock if it contains gold among its minerals. The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if youre able to obtain some, though this is dangerous. While both mercury and cyanide can be used to extract gold from rock, it's hazardous to both your health and the environment to use them.

Variation: The best way to crush the rocks is to use a crushing machine, which will produce a fine powder with little effort on your part. Consider purchasing a rock crusher designed for extracting gold if youre serious about prospecting.[4] X Research source

Warning: Heating the mixture releases mercury in the form of a gas, so work in a ventilated area and wear safety gear. The potato can absorb the gas, but its still dangerous to heat the gold and mercury amalgam.

Prominer maintains a team of senior gold processing engineers with expertise and global experience. 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.

extracting tungsten from wolframite gold ore

The present great demand for tungsten due to world conditions has resulted in an increase of tungsten ore dressing problems for our metallurgists. The flowsheet study shown here was recently developed for treatment of a very complex tungsten-gold ore.

The flowsheet study previously shown for tungsten was devised for a simple tungsten ore free of other heavy minerals. The first consideration of any tungsten ore is to recover the mineral as coarse as possible and avoid sliming and overgrinding by stage crushing and grinding. This is necessary because of the friable nature of all tungsten minerals. This fact was kept in mind for the study shown here, but the problem was complicated due to the occurrence of iron sulphides and free gold with Scheelite.

Straight gravity concentration of this ore, using the flowsheet shown, would result in a mixed gold-tungsten concentrate containing much sulphide which is not desirable for marketing. Consequently, it is evident that other concentration processesmust be incorporated in the flowsheet to produce separate marketable concentrates of tungsten and gold. There are numerous possibilities that could be applicable to this problem, but the described flowsheet offered the greatest degree of flexibility.

The crushing section is designed to remove the undersize between each crushing step and thus prevent excessive production of fines. Primary crushing is accomplished by the Forced Feed jaw Crusher which discharges to a conveyor and then to a Vibrating Screen. The screen oversize is crushed in a secondary cone crusher and the crushed product returned to the vibrating screen.

Crushing Rolls (with large diameter shells) could be employed in place of the cone crusher and in some cases, would probably be preferable. Note the ingenious features of this crushing circuit whereby the jaw crusher and cone crusher products are conveyed to the vibrating screen on common belt conveyor. This arrangement requires one less conveyor belt than old- style crushing flowsheets.

The vibrating screen undersize passes to a fine ore bin for storage prior to grinding. A possibility not used in this flowsheet but sometimes advisable, is to remove the approximate minus 10 mesh fraction from the crushed ore and treat this product on a Mineral Jig prior to grinding.

The crushed ore from the fine ore bin is ground in a Rod Mill to free the minerals with as little sliming as possible. The rod mill is of the special grate-discharge type which is extensively used for tungsten and many non-metallic ores where overgrinding is a serious factor.

The free sulphides, gold and tungsten, are removed in the grinding circuit by means of the Mineral Jig. This jig is selective in its action and is particularly suited for the recovery of fine mineral as well as coarser particles in a high grade product. For simplicity, retreatment of the jig concentrate is not shown, but this includes regrinding with the possibility of amalgamation, flotation, and cyanidation to produce gold in either concentrate or bullion form and a high grade Scheelite concentrate.

In some cases the treatment of the jig concentrate may not require additional grinding but can be subjected to roasting followed by magnetic separation to remove pyrite. Magnetic separation may also be employed to concentrate Wolframite or other magnetic tungsten minerals, such as Ferberite and Huebnerite. Scheelite, a calcium tungstate, is non-magnetic.

The classifier overflow passes by gravity to a Super-Agitator and Conditioner prior to Sub-A Flotation. The object of the flotation section is to remove the remaining fine gold and sulphides before table concentration for the recovery of tungsten. A rougher concentrate is shown, but this can be cleaned, and a high grade concentrate produced in the same flotation machine, provided that a Sub-A Flotation Machine is used.

The flotation tailing is hydraulically or mechanically classified and tabled to produce a finished high grade tungsten concentrate, a middling product, and a final tailing. The table middling is pumped back to the rod mill for regrinding after being dewatered in a spitz-type dewaterer.

The overflow slime product from the hydraulic classifier is thickened in a Spiral Rake Thickener and treated on Buckman Tilting Concentrators to recover the extremely fine tungsten mineral. These Tilting Concentrators play a most important part in recovering the mineral in the fine size range. The concentrate from the Tilting Concentrators is cleaned on a half-size table to produce a final tungsten concentrate. It is considered a must to use these Buckman Tilting Concentrators for recovering fine, heavy minerals at low cost and without the need of specially skilled operators. Mill results are accurately controlled by means of Ore and Pulp Samplers at strategic points throughout the circuit.

When treating tungsten, consider using a Mineral Jig (Pulsating Selector) ahead of the Ball Mill. Friable tungsten minerals may be concentrated at this point in the circuit avoiding possible slime losses.

The flowsheet shown here, wherein a mineral is recovered as soon as it is freed, utilizes the basic concentration principles for tungsten but is complicated by the complex nature of the ore. To insure success, an ore test in the Ore Testing Laboratory is always recommended. While the flowsheet shown is for a specific ore, it is sufficiently flexible to be adapted to other ores with slight modifications.

Materials, Wolframite was obtained from Jiangxi, physically purified and ground in porcelain mill, getting -10 m microsize by a sedimentation. The sample was assayed for 71.57% WO2. The quartz sample (-19 m) was purchased from changsha mineral preparation Co, contains 99.4% SiO2 and 0.6% impurity. Some was acid-treated and washed with distilled water repeatedly until no any traces of Cl- ion being detected.

The synthetic polymers of nonionic, partially hydrolyzed (30%) and sulphated (40%) polyacrylamide (PAN, HPAN, PANS) were used as floccuants in SFGS process. Collectors of styryl phesphonic and benzyl arsonic acid were also accepted in the test.

Polymer Flocculation, Sedimentation was used in a similar way as described by Sresty and Somasundaran to measure flocculation response to single mineral in the suspensions. The flocculation efficiency Ef was referred to the work J.Chen, et al (1988).

The flocculation respone of polymers, CF, (PAMS : HPAM = 1 : 1), CF, (PAMS : PAM = 1 : 1) and PAMS, is given in Fig.2 It can be seen that CF, is the best choice among these polymers. The reason that co-reagents promote Ef is association between polymers, crystal defections on wolframite. Polymers look inactive with quartz.

The PH of pulp can regulate electrokinetic eviornment to enhance the performance of polymers to greater extent. CF, is effective in PH 3 8.5, but HPAM as below PH 7. It illustrats that co-reagent can extend PH ranges. Theoritically, the PZC of wolframite is 2.6-2.8, and PZC (quartz) is 1.8-2.0. If media PH>PZC, the mineral is negatively charged. The potential curves similar to horse saddle are shown in Fig.3 with Electropenetrater.

The adquate dispersion before flocculation affects flocculation response. The test results show that the addition of Na2SiF6, CMC can keep higher level of Ef in dosage of 580 mg/L, but (NaPO3)4 greatly depresses wolframite over 6mg/L dosage. Water glass added in suspension must be precisely controlled, or wolframite is generally depressed in alkaline medium.

For polymer-flocculated systems, agitation is necessary to provide adquate mixing of polymer with the suspension, and to improve particle-polymers and particle-particle collisions leading to destabilization and floc growth. Excess agitation has usually broken up flocs. It is found that good Ef occurs in the stirring rate 900-1200 r.p.m. over 3 min.

Floc is different from common mineral particles. It is characterized as follow, coarser size distribution, less in shape coefficient and density, easier in degradation. Ideal case should be such that valuable mineral is selectively flocculated completely, but associated gangue is adequately dispersed in studied systems. Unfortunately, the gangues are partially flocculated due to poor selectivity of polymers.

The reason with higher E, by SFGS process for natural minerals or mixture is that, interaction between gangue and modified polymer is mostly physical adsorption, thus formed flocs in suspension are larger in porosity and weaker in its strength. However, valuable minerals, relatively speaking, is stronger in floc structure and less porosity due to chemosorption between the mineral and polymers. This will provide advantageous conditions for separating flocs. Consequently, the difference of relative density between two kinds of minerals is greatly enlarged before and after flocculation. Under weak shearing produced by the a-tion of flow or mechanical forces, Bagnolds repulsive forces facilite separatory results of flocs.
