摘要：
A method to reduce the negative effect of copper in the gold cyanidation process is considered. The necessity of establishing the belonging of gold-bearing ore to one or another technological class for an objective understanding of the complex nature of the studied raw materials with the simultaneous determination of the principle diagram of its processing is substantiated. The results of laboratory studies of the possibility of preliminary flotation recovery of sulfides prior to leaching according to traditional schemes are presented. It is proved that due to the technology of selective extraction of copper sulfides from gold-bearing ore, the negative effect of copper on the process of gold cyanidation is reduced.
