South Africa Copper Processing Plant

Extraction would be the operation of physically removing ore from deposits inside the earth. You'll find 3 basic procedures of extracting copper ore: surface, underground, and solution mining. Surface and underground mines typically operate independently of every single other, despite the fact that underground approaches are from time to time applied ahead of and/or soon after surface methods. Some open-pit surface operations extract massive sulfide deposits and intersect abandoned underground workings that were closed as a result of the low grade of oxide and sulfide ore.

South Africa copper ore pulverizing

Copper ore is constantly flowing in and out of the copper grinding mills. The outflow passes through a set of vibrating screens and a water spray. The last screen has 10 mm x 20 mm slots in it. Anything that goes through this last screen or is washed off the bigger chunks by the water spray goes onto the ball mills.

In the copper grinding mills, the ore is crushed into particles of less than 300mm and then ground to a slurry of less than 0.1mm. The slurry is then pumped to flotation plant where various minerals get separated. Flotation is carried out in tanks called flotation cells. Different minerals get separated at different stages. The skimmed minerals are dried on disc filters.
