Insitu leach mining involves pumping of a lixiviant into the ore body via a borehole, which circulates through the porous rock dissolving the ore and is extracted via a second borehole the lixiviant varies according to the ore deposit for salt deposits. The effects of gold mining essay. Cyanide heap leaching is the most common technique of gold ...

The gold from the gold thiosulfate complex formed during leaching is dissociated from the thiosulfate and associated with the cyanide to form a gold cyanide complex. Cyanide therefore replaces thiosulfate and, advantageously, the gold cyanide complex is readily adsorbed onto activated carbon or other suitable adsorbent. Online services
