Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock. This process usually takes place inside a mill or other mining facility.

The Vat Leaching Process Vat leaching can be described as leaching in a bathtub inside a building. Treatment of ore is sitespecific as determined by metallurgical tests. Bench scale metallurgical testing of ores for their amenability to vat leaching is similar to that for heap leaching. First, bottleroll tests of finely ground material are run.

Chemical Leaching. Chemical leaching makes use of the chemical properties of gold to leach it from ore, concentrate, or tailings. This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost.

Sepro Mineral Systems designs and supplies complete, customizable mineral recovery circuits incorporating leaching, gravity concentration, agglomeration, and electrowinning based on mining project requirements. Laboratory units are also available for agitated leach reactor testing which generate reliable data for scale up to commercial operation.
Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple process, involving a vat of wellmixed neutralized sand, ample contact with strong and weak ...
3. CarbonInLeach (CIL): The carboninleach process integrates leaching and carboninpulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.
Oct 20, 2014· That much is straight forward. However, there are a large number of critical factors which together determine the success (or otherwise!) of gold leaching in a mineral processing plant. Here is a summary of some of the key variables usually considered in the design of these cyanide leaching .
Hydrometallurgy is a method for obtaining metals from their ores. ... The five basic leaching reactor configurations are insitu, heap, vat, tank and autoclave. Insitu leaching. Insitu leaching is also called "solution mining." The process initially involves drilling of holes into the ore deposit.

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...
