The pulp is fed into the second cell of each bank and a sulphide rougher concentrate is produced from cells, 2, 3 and 4 and returned to the first cell for cleaning. This cleaned sulphide copper concentrate is pumped by 3″ x 3″ DRL Pumps to the main sulphide cleaner concentrate pump box and thence to thickeners.

Copper Life Cycle. From its original home in the earth's crust, copper passes through several stages to reach a long life in essential products like electronics, appliances, electrical grids, vehicles and renewable energy technologies. As a recyclable material, copper can be reused over and over again with no loss to its physical properties.

Refining. The first step in the copper manufacturing process is refining. Copper ore that is mined from the earth is typically mixed with other minerals, such as iron, sulfur, and silica. This mixture is then heated in a furnace to a temperature of 2,000 degrees Fahrenheit. This process removes most of the impurities from the copper ore and ...

The SX/EW Process. The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal. Because of its dependence on sulfuric acid, the SX/EW Process is at present not a substitute for, but ...

Copper processing - Refining, Alloying, Extraction: The major portion of the world's production of copper is utilized by electrical industries; most of the remainder is combined with other metals to form alloys.
