  • Extraction Of Copper Mining, Concentration, Smelting

    The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulfide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag. Iron in Chalcopyrite is removed as Iron silicate slag. Most of the sulfur in Chalcopyrite turns into Sulphur dioxide (SO 2).Copper Mining and Extraction Sulfide Ores,Stage 3: Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.

  • Chalcopyrite Leaching Metallurgist & Mineral Processing

    Leaching Chalcopyrite is the holy grail for hydrometallurgists (Leachers), difficult to leach as the sulfur forms a layer over the mineral and makes the leaching slow. Having said that, it is not 100% not leachable, not unusual for ore dumps (low grade) containing chalcopyrite to be placed under leach but report low recovery +/-30% TCu over several years and the rate is around 0.5-1% per monthCopper Smelting Chemistry Tutorial,Example: Extraction of Copper From Chalcopyrite (CuFeS 2) Mining : digging or blasting to obtain the copper ore from the surrounding rock Crushing : mined copper ore is crushed into very small pieces ; Grinding : crushed copper ore is ground into a powder; Concentrating by flotation (also known as froth flotation or as ore flotation).
