Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it's screened and fed into the ball mills.
SAG mill can be applied as the first stage grinding equipment. It can effectively avoid the occurrence of sliming phenomenon, and avoid further grinding of fine particles. It can play a good role in controlling granularity and energy saving. Infrastructure investment and equipment cost is lower than common process; The unit grinding cost of ore ...
