Foundry Sand Production System Chromite
Foundry Sand Production System Chromite. For the production of ferrochromium the chromite ore FeCr 2 O 4 is reduced with either aluminium or silicon in an aluminothermic reaction and for the production of pure chromium the iron has to be separated from the chromium in a two step roasting and leaching process.

Chromite (Cr2FeO4) | CrFeO4
Sand used in the foundry industry is washed, graded, and dried. Since silica sand is common and inexpensive, it is the most commonly used mineral. However, when physical or chemical conditions dictate, other sands are chosen, such as zircon, olivine, or chromite. Chromite foundry sand is used in the ferrous and copper casting industries.
