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 sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at …

 — A much more difficult mineral processing challenge is the selective flotation of arsenic-bearing copper minerals (e.g., enargite, Cu 3 AsS 4, and tennantite, (Cu, Fe) 12 As 4 S 13). These minerals have flotation characteristics very similar to non-arsenic-bearing copper minerals (chalcopyrite, chalcocite and bornite).

 — The specifications of copper ore rock: Different kinds of copper ore have their own unique physical and chemical properties. Also due to the different percentages of copper in the ore rock, we need to make sure whether it is valuable or not to be processed at very beginning of the processing.

There are two big opportunities for DES in copper processing: first, the processing of copper deposits in jurisdictions with water usage sensitives and, second, the processing via leaching of transition ores and copper …
