The extraction and strip circuits may each contain several stages, through which the aqueous and organic streams flow in counter-current directions (see Section 16.6). (a) In the extraction process, the PLS (feed to the SX process; 1–10 g/L Cu 2+, 0.5–5 g/L H 2 SO 4 ) is contacted with an organic phase containing a Cu-specific organic .

The crushed copper ore (containing, for example, 0.75% Cu and 0.015% Mo) is fed to the grinding circuit where water is added and the ore is ground to the proper size. Lime and an oil for collecting molybdenum are usually added in the grinding circuit. A copper collector may also be added at this point. The pulp progresses to the flotation cells.

Crusher - Wikipedia

Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
