In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore.

The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation.
Chromite Ore Grinding Mill, chromite ore production line ... Chromite ore beneficiation begins with the milling of extracted ore in preparation for further activities to recover chromite values. Milling operations are designed to produce uniform size particles by crushing, grinding, and wet or dry classification.
May 10, 2019· Grinding mill medium is the main factor affecting grinding efficiency. In industrial production, the type, shape, size ratio and filling rate of grinding medium should be determined according to the grain size characteristics, hardness characteristics and product particle size requirements of ore materials.
These data indicated that when high chrome grinding media was substituted for forged media when grinding a refractory gold ore, the pulp chemistry shifted to more oxidising conditions. This shift was accompanied by a reduction in the EDTA extractable iron levels in the pulp, and an improvement in the flotation performance.

Chromite ore can be mined to produce chromite concentrate. It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron.

Supply of world chromite (chrome ore) has come under severe pressure over the past year driven by strong demand for ferrochrome used in ferroalloy production for making stainless steel.
Grinding times will also vary sample to sample, the testing should be done in order to see if the grinding time shows them as adequate. Grinding time can be increased in specified intervals and retested; the optimum grinding time can be timed when the analysis does not change significantly when more grinding time is added.
