Most gold deposits occur associated with sulphides like pyrite and arsenopyrite; thus precious metal dissolution is possible by oxidizing auriferous sulfide concentrate using simultaneous pressure oxidation and cyanidation The effectiveness of this process of extraction can be influenced by the temperature cyanide NaCN concentration and oxygen pressure In

A contribution to documenting current and future best practice in gold ore processing seems focus of this volume is on advances in current gold plant operation from conception to closure; chapters also cover innovations at the bench and pilot scale level that would be expected to find commercial application at some stage
In recent years the gold mining industry has been challenged by declining metal prices as well as having to treat ores that have low grades and are refractory in nature Many factors must be considered when metallurgical studies are designed to develop process design criteria for these type of ores These factors are mostly related to the mineralogical and
Having successfully used and proven its evaluation process over some 85 years of operation Rand Refinery remains convinced that the melting of gold and silver dor receipts in an induction furnace is imperative in order to obtain a completely representative sample of gold and silver content for analysis Of special importance to gold refineries is the segregation in
