The AG mill circuits have not been able to sustainably achieve the design capacity of 30,000 t/d of underground ore. Thus, a fraction of the underground ore is diverted to the conventional circuit. The conventional circuit consists of crushers, rod and ball mills and traditionally has achiever lower copper recoveries than the AG circuit.

The hammer crusher , also called the hammer mill, is an example of an impact crusher. Types of tumbling mills include rod mills, ball mills, and tube mills. since the crystal size in the material is very small due to the rapid freezing, there is less damage done within the cells. This creates a high quality product .

1. Introduction. Nowadays, with the increasing depletion of high grade and coarse-grained ores, the trend is towards the extraction of low-grade ores .This can have two consequences for the minerals industry; first to process larger tonnages of mineral raw material and second to grind the raw materials to finer sizes , which in turn leads to higher energy consumption.
