Method of recovering copper from ores |
| abstract |
The invention relates to non-ferrous metallurgy and can be used to extract copper from ores. The purpose of the invention is to reduce the cost of the process and the utilization of waste gas. This is achieved due to the fact that the ore is sulphidized with autogenous flame retard gases when the mass ratio of oxidized copper in the ore to sulfur in the recovered gases is 1: (0.5-1.5). 1 tab. |
