Subsequently, copper is refined in the melt flow and by electrolysis, with refining without subsequent electrolysis only a share of about 10% has. In fire refining, impurities are removed by blowing air in the refining furnace and then the last remaining sulfur is removed by "poling" the liquid copper matte in the rotary furnace (anode furnace ...

Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating …See more on superfund.arizona.edu

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
