There is currently much interest in how extraction of gold and silver from ores with acidic thiourea solution compares with extraction using alkaline cyanide solution. Agitation leaching tests were performed by the Bureau of Mines on 14 precious metal ores using sodium cyanide (nacn) and thiourea [(nh2)2cs] as extractants. The objective was to compare the results of the two extractants.
