COPPER Copper production - TU Delft

Copper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for
