cyanide gold leaching machine

Gold extraction Wikipedia

Thiosulfate leaching has been proven to be effective on ores with high soluble copper values or ores which experience pregrobbing: the absorption by carbonaceous components which preferentially absorbs gold and goldcyanide complexes. Leaching through Bulk Leach Extractable Gold, or BLEG, is also a process that is used to test an area for gold
