Mill Process Plant consist of 4 concentrators such as Concentrator #1 and #2 (also called North and South Concentrator), Concentrator #3 (SAG1) and Concentrator #4 (SAG2). The main function of this processing plant is to increase the metal grade by separation of valuable metal (mineral) from their gangue.

A notable fact is that the energy efficiency of conventional milling is only about 1%, as mentioned in Sect. 1. An earlier experimental study indicated that about 8090% of the energy input of a ball mill was used in heating the material (Schellinger 1951, 1952), and a recent study showed that over 75% of the electrical energy was used to heat the slurry (Bouchard et al. 2016).

ABSTRACT Like many operations, the Mt Isa Copper Concentrator occasionally has operational periods when it is difficult to achieve target grade and/or recovery, often due to feed ore type changes as mine production is drawn from different stopes in the underground mine. At times like these it is useful for metallurgists to have a suite of tools that they can use to quickly diagnose the problem ...

The purpose of the concentrator is to reduce that percentage so that it can he economically he shipped to, and treated by, a smelter. To accomplish this the mineral must be liberated, prepared, separated and finally dried for shipping.
