Extraction Of Copper Mining, Concentration,
Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is Trace quantities of residual copper are reduced to levels of <0.04 mg/l by ion exchange using a chelat- ing resin because it poisons the extractant used in the subsequent extraction operation andTypical solvent extraction flow sheet.

Extraction of Copper: Detailed Process The Chemistry Notes
Modern smelters are designed to collect at least 90 percent of the sulfur in the feedstock. These steps result in the following reaction: 2 CuFeS2 + 2 SiO2 + 4O2 → Cu2S + 2 FeSiO3 + 3SO2. Copper extracted by this method is combined with slag to create a material known as Matte Copper due to its matte look.The use of seawater is projected to increase to 11.0 m3/s by 2030, representing approximately 47% of the water required by copper mining (COCHILCO, 2019).Simplified flow-sheet of pyrometallurgical process for copper

Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate (Optional partial roasting to obtain oxidized material or calcines) 2. Two-stage pyrometallurgical extraction 1. smelting concentrates to matte 2. converting matte by oxidation to crude (converter orcopper concentrate flow chart.
