The leaching and passivation of chalcopyrite in acid

Sulfate-based leaching processes for chalcopyrite (CuFeSa) are attractive because of their inherent simplicity. Unfortunately, high copper extractions are not attainable in a reasonable residence time unless the leaching temperature exceeds 200C (oxygen pressure leaching) or chalcopyrite is activated by a pretreatment method prior to leaching. In the present work,

Extraction Of Copper

Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.
