Rethinking the value of mill relining Mining Magazine

03/11/2016· This unprecedented high price for gold meant that many large low-grade ore deposits were now commercially viable mining propositions. Semi autogenous grinding (SAG) mills, because of their advantages in terms of capital and operating costs, were the natural choice for mines as their primary grinding mill option. Then, in the late 1980s when the price of copper rose quickly from a low of $0.62

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. change in ore characteristics (ore feed rate, grindability, feed
