Gold Silver

Heap leaching is generally used to recover gold from lowgrade ore, while tank leaching is used for higher grade ore. Cyanidation is the primary means of recovery of fine gold and silver. In this process, solutions of sodium or potassium cyanide are brought into contact with an ore, which may or may not have required extensive preparation prior to leaching. Gold and silver are

The Borax Method of Gold Extraction for SmallScale Miners

mercury. It is also less expensive. It is important to stop the use of mercury amongst SSM. However, health and environmental arguments alone are not enough to convince miners to switch. The argument of improving goldcapture rates while reducing costs is more compelling, and may help propagate the technique among smallscale miners. Conclusions.

Cyanide Leaching Of Gold, Laboratory Bottle Tests

Use a lab mixer or stirrer to continuously mix the solution for about 30 minutes. Using a 500 ml graduated cylinder, measure out 300 ml of the solution for use with the leach test. Now, with the 300 ml cyanide solution and the 100 g of ore in the bottle, place the lid on firmly, making a seal.
