Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_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 ...

The increasing demand for copper and the depletion of primary resources have urged researchers and industrialists to explore secondary resources, copper slag being one of them. Generally, copper is mined from ores containing 0.4–0.8% Cu [47]. Copper metal is produced from these ores following a pyrometallurgical route of smelting or converting.
