The following is a process of copper extraction from chalcopyrite ore into pure metal. While oxide ores can be processed using pyrometallurgical techniques hydrometallurgical methods are more cost effective. The copper ore is crushed and ground before it is concentrated to between 20 and 40 copper in a flotation process.

Techniques using the process of copper plating with a copper sulfate solution relate to choosing an ideal water to copper sulfate ratio. The amount of copper sulfate in the solution is limited by the water saturation capacity so once the solution is mixed in and the water no longer causes it to dissolve and instead causes it to settle to the bottom of the vessel maximum saturation has been

Copper Mining The commonest ore used in the extraction of copper is Chalcopyrite CuFeS 2 also known as Copper Pyrites and other such sulfides. 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. Concentration of Ore
