COPPER Copper production - TU Delft

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.

Kell Process

The hydrometallurgical process has been successfully demonstrated on several different PGM and polymetallic concentrates, including those from the UG2, Merensky and Platreef in South Africa, Great Dyke in Zimbabwe and several concentrates from North and South America.

Beneficiation - an overview | ScienceDirect Topics

A simple process of beneficiation has been selected, which will be low in capital cost. As the scheme is a simple one, the cost of operation and maintenance will be minimal. The process technology is so chosen that it should be able to meet the quality parameters laid down by consumers. The flow scheme is briefly described here:

Beneficiation of alunite by pyro- and hydrometallurgical ...

Abstract. High-temperature roasting of alunite in the presence of K 2 CO 3 gives rise to a reaction that results in up to an 80% recovery of its potassium content as K 2 SO 4 by leaching of the roasted mixture. K 2 SO 4 is also generated from the reaction between the added K 2 CO 3 and the S0 3 driven off during roasting of the alunite. This limits the environmental and corrosive problems ...
