摘要：
The behaviour of elemental sulphur in the biooxidation process of arsenopyrite and pyrite has been investigated. It was found that the α- S0 produced in the bioleaching residue of arsenopyrite was formed by the process of chemical oxidation, while little sulphur was detected in the bioleaching residue of pyrite. The reason for the high consumption of cyanide for the bioleaching residue of Banbishan gold concentrate has been studied and a pretreatment method has been suggested to improve the cyanidation process.
