Abstract Thiosulphate is an attractive alternative reagent to cyanide for processing gold ores. It is relatively cheap and non-toxic, forms relatively strong gold and silver complexes, and readily leaches gold ores in ammoniacal solutions, catalysed by Cu(II). It is particularly suited to carbonaceous ores where the recovery of gold by cyanide is poor.

with gold molecules. With many sulfide ores, the ore cannot practically be ground down fine enough to expose the gold particles. The objective of pretreatment for these ores is to remove enough of the sulfide so that at least a small portion of all gold particles are directly exposed to the elements. Processes available for treatment all

A Review on Alternative Gold Recovery Re-agents to

2016-8-18  The importance of gold recovery from low grade ores and flotation tailings is continuously increasing due to raising gold demand and thereby high gold prices. However, due to raising social awareness of the ecological impacts of cyanidic gold extraction and environ-mental specifications, the development and the implementation of alternative hydrometallurgical extraction processes have been

Methods of Processing of the Gold-Containing Refractory

2019-8-9  Alternative methods of processing the refractory gold-sulfide ores and concentrates were worked out. The gold-containing refractory sulfide ores of chalcopyrite, pyrite, barite-polymetallic, quartzites, copper-zinc, antimonite were used in the research. As a result of investigation, the optimal
