  • How Hydrometallurgy and the SX/EW Process Made Copper

    2021-1-21 · In addition the process can be used to extract copper in situ. That is without removing the material from the waste pile or from the ground. The net result of the use of this process is that copper can be produced from sources that in the past would have gone untouched thus reducing the reliance on conventional ore bodies.

The minerals in copper ores are reduced to copper through mixing carbon with the ore and heating the combination to about 1 100°C. (This can be done directly with copper oxide ores. Copper sulphide ores are heated in contact with air first.)
