Copper Mining and Extraction Sulfide Ores

This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace. The liquid left is a mixture of copper sulfides and iron sulfides. It ...

Spence Copper Cathode Mine, Atacama Desert, Chile -

The operations at Spence comprise an open pit mine, sulphide leaching and oxide processes, and an SX-EW process. Ore is crushed, agglomerated, and transferred to leach pads at a rate of 50,000t a day. Sulphide and oxide ores are leached on separate dynamic (on / off) pads. Solvent extraction relies on four trains in a series-parallel configuration with extraction stages for both oxide and ...

Copper Mining and Extraction Copper Mining Processing

Copper is extracted in large amounts from the Earth’s crust by mining of sulphide ores and also oxide ores. Studies reveal about 80% of copper is produced by its extraction from sulphide ores. Chalcopyrite is a certain kind of suphide ore that can be converted to copper by a different method from silicate, carbonate or sulphate ores. Generally, the method used for the extraction of copper ...
