Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.

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. The grinding process reduces the rock to a slurry.

Grinding this ore in an iron mill reduced the natural floatability of sphalerite significantly. Many industrial circuits also showed significant effects of milling on sulphide flotation (Kocabag and Smith, 1982, Forssberg et al., 1988 and Forssberg et al., 1993). The depression of sulphide flotation after milling in a steel mill, which typically results in a less oxidising environment, could ...
