Recovery Methods As Related To Properties Of Gold Ores

In this Monograph are presented operating data, operating costs, plant descriptions, and detailed flowsheets of twenty seven different cyanidation plants around the world. Twenty three of these are gold producers and four are primarily silver producers. With one exception, (Pueblo Viejo scheduled to start up in late 1974), all of the plants are operating at the time of this writing. Selection of operations was based on metallurgy and were grouped into free milling lode ores, other free milling ores, ores requiring sulfide flotation in addition to cyanidation, ores requiring roasting, telluride ores, South African ores, and silver ores. Each of the plants described illustrates some unique form of cyanidation metallurgy. It is the hope of the authors that publication of this Monograph will be an aid to metallurgists in bringing new and successful cyanidation ventures into operation.
