Ball Mill in Copper Concentrator Plant

Ball Mill in Copper Concentrator Plant

The first step in beneficiation is comminution by crushing and grinding. In grinding operation, ore particles are reduced and classified into a uniformly sorted material between 20 and 200 mesh. Most copper facilities use a combination of rod and ball mills to grind sulfide ore. Rod mills use free steel rods in the rotating drum to grind the ore.

Ball Mill in Copper Concentrator Plant

The optimisation project explored circuit alternatives such as varying the number of SAG and ball mills. Low capital investment alternatives such as the optimisation of the SAG mills liner design, pulp lifters, ball charge level and ball size were studied in the SAG mill circuit as well as an optimum circuit configuration for the ball mill circuit and classifiers.

The copper concentrator grinding circuit currently consists of two semi-autogenous mills, followed by two ball mills. The copper concentrator primarily treats chalcopyrite ore from open pit or underground copper mines, but on occasions it also mills copper smelter slag to recover the contained copper. The grinding and flotation circuits can be operated either as two separate lines or combined.

Ball Mill Application

A ball mill works by tumbling the ore against free steel balls and the lining of the mill. It is a versatile grinding mill and has a wide range of applications. The mill can vary in size from small batch mills up to mills with outputs of hundreds of tonnes per hour. They are the most widely used of all mills. Small hand operated ball mills are used for preparation of ore, sand and gravel.
