Abstract
The ore from Baiyinchagan mine is typical increasingly refractory as the mine get deeper, especially the increasing lead and zinc contents, which not only detrimentally affects the product quality of copper concentrate, but also results in the loss of lead and zinc resources. In order to solve the problem, two routes were conducted: first, depress liberated lead and zinc minerals from the raw ore; second, float lead minerals from the copper concentrate. Sodium sulfide was used as detoxification, polysulfide-as copper depressant and diethyldithiocarbamate-as lead collector. The quality improvement and efficiency of copper rough concentrate were realized.
