copper sulfide ore， copper sulfide - Xinhai
2021-4-15 After the first stage of grinding, the copper sulfide ore in the one-stage grinding-flotation process would reach a fineness of 50-60% -200 mesh and would be basically dissociated. Then the copper ore enters the flotation stage, and better flotation indicators can be obtained through one roughing, one scavenging and one to three times concentrating.

Mechanochemical sulfidization of a mixed oxide
Mechanochemical sulfidization by co-grinding with sulfur was developed for treatment of a sulphide-oxide copper ore. A 0.5 wt.% sulfur led to the higher floatability of copper owing to the formation of Cu—S bonding on copper oxides surfaces.

2019-7-9 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.
