  • Copper Mining and Processing: Processing of Copper Ores

    Sulfide ores are generally processed using pyrometallurgy, the extraction and purification of metals by processes involving the application of heat. This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.

  • 12.3 Primary Copper Smelting

    Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.

  • Copper ore processing

    Leaching process for copper ore includes acid leaching and ammonia leaching. Leaching process is mainly for oxide copper that is very difficult to be extracted by flotation. Also for some copper ore it is combined by both oxide copper ore and sulfide copper ore, after processing test combined processing technologies can also be adopted to extract copper.
