The ore contains on average 1.1% sulfide sulfur, 1.1% organic carbon and 2.9% carbonate carbon. The relatively high carbon content affects the gold recovery through preg-robbing during leaching. After roasting in the CFB, the carbon content is reduced to such low levels that the gold recovery increases by approximately 20%.

Electrochemical oxidation 28) uses electrodereaction to oxidize gold ore bearing arsenide and sulfide in a certain media. The dielectric system contains vitriol, nitric acid and hydro-chloric acid, etc. The result of reaction is similar to pressure oxidation. The process can change microstructure of refractory gold ore to improve porosity of ore.

Sulfide ores. Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leaching.These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.. Supergene ores rich in sulfides may be concentrated using ...

Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.
