Gold recovery and refining Companies need successful recovery methods that drive profits. Design teams with extensive experience incyanide-in-leach(CIL), cyanide-in-pulp (CIP), carbon elution, carbon activation— in addition to newerthiosulfateleaching and regeneration processes—can enhance gold recovery and profitability

processing, smelting and refining gold | world gold council

Cyanidation.More gold is recovered bycyanidationthan by any other process. Incyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore),cyanidationis accomplished by vat leaching, which involves holding a …

continuous vat leaching (cvl) & glycine leaching

TheGlycine LeachingProcess is an environmentally benign hydrometallurgical process that will leach base and precious metal oxide, mixed oxide and sulphide ores. Glycine is the simplest and cheapest amino acid, and is available in bulk in different grades. It is an environmentally safe and stable reagent and is biodegradable and easily metabolized in most living organisms
