Copper Sulfide an overview | ScienceDirect Topics

Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu-sulfide

Oxidation of Copper Sulfides and Secondary Sulfide

Oxidation of copper sulfide without complementary sulfide enrichment may occur if little or no pyrite is present to form sulfuric acid or if the host rocks are strong neutralizers of acid. Extreme aridity of climate may result in the formation of soluble sulfates in the oxide zone. The texture, structure, size, and arrangement of limonite grains may be used to interpret leached outcrops and
