Copper Solvent Extraction Amp Electroextraction

Leaching is the process by which the processing of oxidized copper ores is carried out. Diluted sulfuric acid is applied to the surface of the material on leaching pads or in leaching tanks. The leaching solution called pregnant or pregnant liquor is then treated using a solvent extraction and electro-extraction or SX-EW process.

Copper Extraction From Sulfide Ores Latest Contents

This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk about 100,000 tons is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides. The process is completed in about one year.
