Like mining, beneficiation (processing, crushing, separating, smelting, refining, etc.) for chromite depends on the characteristics of the ore deposit and on the mining methods used. For example, an operation extracting only high-grade ore may require only hand sorting and screening.

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.

The selection of chrome ore mining equipment is closely related to the physical and chemical properties of chromium ore. Because chromite is weakly magnetic, with the continuous improvement of high intensity magnetic separation technology, the technology of purifying chromium ore with high intensity magnetic separation has been very mature.
