Mechanism of Cu Ion Targeting Combined with an Organic Depressant To Enhance the Flotation Depression of Pyrite.

In this study, pyrite was used as the research object, and the behavior and mechanism of a copper-ion-enhanced organic depressant in depressing pyrite flotation were studied. Microflotation experiments showed that, after the addition of CuSO and ,-dimethyldithiocarbamate (,-DDS), the floating collection efficiency of pyrite declined from 82.37 to 21.
