EXTRACTING METALS FROM SULFIDE ORES

Another example is the treatment of ores containing copper sulfide (chalcocite) and copper iron sulfide (chalcopyrite), together with molybdenum disulfide (molybdenite). The usual practice is to float both copper and molybdenum minerals in the first stage, leaving iron sulfides and other gangue minerals behind.

copper is extracted and concentrated by froth flotation in which ground ore is mixed with reagents in an aerated tank filled with water.

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfurbearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
