CHLORINATION OF COPPER AND NICKEL SULFIDE CONCENTRATES

Cite this. AB A chlorination process for treating metal sulfide flotation concentrates is described. The process involves low temperature chlorination combined with sulfur chloride conversion and selective oxidation to produce nonferrous metal chlorides, elemental sulfur, and ferric oxide in a three-stage fluidized bed reactor.

Copper Sulfide an overview ScienceDirect Topics

The common route for turning copper sulfide ores into metal is high temperature oxidation of sulfides to produce an impure liquid copper. This is cast into slab-like anodes. Principal impurities are iron and precious metals (gold and silver). The anodes are electrolytically refined in cells sketched in Fig. 8.There is a resemblance to the cell of Fig. 7.
