By 1855 Australian gold diggers were joined on several new leach tanks where a weak cyanide solution is combined with Gold extraction and processing

During the cyanide leach process a cyanide solution or lixiviant is percolated through ore contained in vats columns or heaps Gold is dissolved by the cyanide and then removed from the heap or columns It is then extracted from the pregnant leach solution by adsorption on carbon or resins This cost effective proven method of ore extraction provides maximum recovery for many gold ores

This is a list of gold mining disasters resulting from dam failure cyanide leaking into the environment and inappropriate toxic waste discharge related to gold mining using the gold cyanidation technique

Various methods such as gravity concentration flotation panning pyrometallurgy cyanidation etc are available for the extraction of gold metal from its ores Amongst these methods cyanidation is the most common method used in the leaching of gold from the ore This process involves the dissolution of gold

Heap leaching is an industrial mining process to extract precious metals copper uranium and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re separates 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
