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 processing,extraction,smelting plant design, equipment for sale | prominer (shanghai) mining technology co.,ltd

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.

small gold processing plant

The problem aSmall Gold Processing Plant can solve is for the need to to provide a small, relatively simple and inexpensive gold mill that will operate at a reasonable profit with a minimum of supervision. The limited availability of skilled operating personnel, availability of water and local power, high cost of transporting ore and expense of building, operating and maintaining such a mill have been taken into consideration in developing the flowsheet. A primary objective is to provide a mill having sufficiently low power and water requirements as to be supplied locally.

The flowsheet was developed for a siliceous ore with a high percentage of the gold present in a free milling state. In addition some gold bearing sulphides are present which require the inclusion of flotation in order to obtain maximum recovery. Most of the goldis, however, recoverable in bullion form for shipment to the mint. The gold tied up in the flotation concentrate is shipped to a smelter, although in remote areas a small batch cyanide plant may be used to extract the values and thereby eliminate the shipping and smelter charges.

Single stage crushing for the average small mill (100 tons or less) is adequate. The crushed ore at approximately minus 1 inch is wet ground in a Ball Mill to free the gold and sulfide values. Grinding is in closed circuit with a classifier and in this case a 48 mesh grind was necessary.

To trap the heavy free gold in the grinding circuit a Mineral Jig is placed between the ball mill and classifier. This recovers the gold just as soon as released and avoids its accumulation in the bottom of the Classifier or Ball Mill scoop box. The high grade gold concentrate from the jig is ground in batches and amalgamated in a Amalgamation Unit. The residue from the unit is collected, dewatered, and saved as it usually contains sufficient value for retreatment or shipment to a smelter.

Amalgamation plates are shown in this flowsheet to recover the very fine gold which may escape the jig and overflow the classifier. Amalgam from the silvered copper plates is collected periodically and retorted along with the amalgam recovered from the amalgamated Jig concentrate. Corduroy blankets may be used in place of the plates. The heavy mineral concentrate is ground and amalgamated with the jig product.

The ground pulp after jigging and amalgamation will usually contain 20 to 25% solids which is ideal for flotation feed. This pulp passes to a Conditioner where reagents are added to activate the sulphides and possible tarnished gold values. After conditioning the pulp flows through a Sub-A Flotation Machine of the cell to cell type. The flow arrangement is typical for small plants where the ratio of concentration is high. If more cleaning is necessary, the feed may be introduced into the second cell and the final concentrate taken off Cell No. 1. Reagents for gold flotation are simple and usually consist of soda ash, a xanthate, and a frother.

All concentrates including the amalgamation residue are pumped to a Disc Filter for dewatering. Filtering may be direct without thickening. If the quantity of concentrate is appreciable and filtration rates low, a Thickener ahead of the filter is advisable.

Flotation tailings are finally tabled for recovery of oxidized values. This product may be added to the flotation concentrates, or if some free gold is present, it may be amalgamated along with the Mineral Jig concentrate. The Table also serves as a pilot control of the mill circuit both as to grind and recovery.

In this example the concentrates from the Mineral Jig and Table were combined and amalgamated to give the above recovery in amalgam form. With amalgamation plates in the circuit as shown, the recovery of gold in bullion form should approach 80%. The balance of the recoverable gold is in concentrate form for shipment to the smelter. In the example shown the combined shipping product (residue plus flotation concentrate) assays 6.45 oz. gold per ton. From 50 tons milled, 2.88 tons of concentratesare produced.

The developed flowsheet provides a Small Gold Processing Plant which can be efficiently operated by one operator per shift or with a helper if local requirements so dictate. Power requirements are such as to be available from a portable generator and water requirements are held to a minimum.
