copper regrinding mill circuit flow sheet


When it Comes to Mining, Bigger is Best

comminution circuit providing high throughputs can be seen in (Fig. 3). This circuit, however, has a high, specific energy consumption per ton of ore pro-cessed, driven primarily by the low ef-ficiency of the ball mills and the need to use steel media for grinding. Ring-geared mill drive. Throughout the comminution process, different mills are ...

Grinding Mill - an overview | ScienceDirect Topics

The principle objective for controlling grinding mill operation is to produce a product having an acceptable and constant size distribution at optimum cost. To achieve this objective an attempt is made to stabilize the operation by principally controlling the process variables. The main disturbances in a grinding circuit are: 1.

Grinding Mills - an overview | ScienceDirect Topics

The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).
