بيت /processing of nickel ores and concentrates
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 ( – 1 % Cu) must be concentrated by beneficiation.
