Chromite - Wikipedia
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.

How to Recover Chromite
The chromite content varied in the different size fractions and is listed in table 4. Chromite gram analyses ranged from 60 to 70 pct Cr2O3. Liberation was measured by grain counting and was performed on all the size fractions. This ore began to show chromite liberation around 20 mesh and was nearly liberated at 65 mesh.
