Silver amp; Gold Cyanide Leaching of Copper OreMuch work has been done on the effect of copper in cyanide solutions on the leaching of gold. It is generally accepted that copper in cyanide solutions can form complex ions such as Cu(CN)2 , Cu(CN)3=, and Cu(CN)4= , although Cu(CN)3= is considered the most probable of these.Gold cyanidation Cyanide leaching quot;heapquot; at a gold mining operation near Despite being used in 90% of gold production gold cyanidation is controversial due to the toxic nature of The Metallurgy of Cyanide Gold Leaching An IntroductionLeaching gold with a cyanide solution rema
