In this process, the high tendency of cyanide to complex with gold and silver results in the dissolution and removal of these precious metals from ore bodies; however, the affinity of cyanide to react with other metals in the ore results in its consumption (Norman Raforth, 1994). The released wastewater from the mining industry may contain metalcyanide complexes. The change of pH or ...

 · This process is achieved by dissolving gold or silver in either a potassium cyanide or sodium cyanide solution. Mining companies also incorporate the use of a technical extraction process in the extraction of gold. Larger pieces are broken down into much smaller pieces. The removal of silver from its ores also uses the sodium cyanide process, just like gold. Gold Leaching. Leaching is used .

Cyanide Process – Extraction Of Gold Through Cyanidation Gold is usually found in low concentration in the form of ore which is mined. Gold should be separated from other minerals present in the ore. As gold is insoluble, it should be separated from other minerals to make it soluble. Hence, sodium cyanide can be added, where cyanide ions form a complex ion with the molecules of gold. The ...
