COPPER Copper production Repository

2008-12-16· Figure 1: Overview of copper production Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 1 % Cu) must be concentrated by beneficiation.
