Extraction of Copper from Copper pyrite | Grade 12 Science Notes

The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.

Copper Smelting Chemistry Tutorial

A copper ore is a mixture of copper minerals and other materials in the rock called gangue, from which it is economically viable to extract the metal. A typical copper ore contains between 0.5% and 2.0% copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal.

The Extraction of Copper - Chemistry LibreTexts

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

Solvometallurgical process for extraction of copper from ...

A conceptual closed-loop process for the extraction of copper from chalcopyrite is proposed . As the above experimental results have shown, copper and iron in chalcopyrite can be extracted quantitatively with the lixiviant FeCl 3 EG and sulfur can be removed as solid elemental sulfur. The metallic copper can be produced by direct electrodeposition from the pregnant leachate without any other competing electrochemical reactions.
