Nov 29, 2019 · Heap leaching is one of the oldest and the most traditional mining process used to extract valuable metals from specific minerals. This is a hydrometallurgical process in which the solution is applied for the dissolution of minerals from the ore that is used for the extraction of metals. Originally, heap leaching was practised 500 years ago.

Bacteria Leaching of Gold Encapsulated in Pyrite

Feb 19, 2018 · The higher the degree of oxidation of pyrite, the higher is the extraction recovery of gold and silver. However, about 74% biooxidation of pyrite was enough to increase the cyanide extraction recovery of gold and silver to 89% and 95% respectively. Use of 12 weeks adapted bacteria virtually eliminates the lag period for bacterial activity.

The SX/EW Process has its roots in analytical chemistry where it is used to separate one metallic ion from another. It was first used as a largescale process during World War II for the recovery of uranium from its ores. The key to the process is the development of organic extractants that are specific to the metal to be extracted.
