Jul 09, 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.Jul 17, sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper, lead, and zinc minerals in their oxidized form. the sulfidization process, developed in the u.s.a. in -20 for oxide copper minerals flotation, is especially suitable for oxidized lead ores in which the gangue is usually.
