In the metallurgical industry, chromium ore is mainly used in the production of ferrochrome and chromium. Common chrome ore chromite, aluminum chromite and chrome-rich spinel several categories, and all belong to the Cr-spinel minerals.

Since chromium is the most versatile metal, and the first column in the "strategic metal". So many countries in the world today are stepping up to the beneficiation of chrome ore. Specifically, the chrome ore beneficiation methods are as follows:

1. Gravity separation: such as jig, shaking table, spiral chute, heavy medium cyclone, etc.
2. Magnetic selection: high-strength field of magnetic separation, high-voltage election.
3. flotation and flocculation and flotation. mini mobile jaw crusher
4. Joint election: If gravity separation - electrostatic separation.
5. Chemical processing: processing of very fine-grained refractory poor chrome ore.

Production in the chrome ore beneficiation methods, mainly re-election, often in the shaker and jig sorting. Sometimes re-election re-election concentrates with weak HIV-election or high intensity magnetic separation to further improve the grade of chrome concentrate and ferrochrome than. It should be noted, high chrome spinel iron or magnetite dense symbiotic ore concentrate obtained by beneficiation, chromium grade and ferrochrome are low, we can consider as the pyrometallurgical production of chromium iron ingredients, or hydrometallurgical processing. ore crushing equipment

Such as sodium dichromate method, chromium hydroxide method to restore the corrosion method, chlorination roasting acid leaching or electrolysis. Hydrometallurgical processing low-level ferrochrome concentrate existing production practices. cement mill plant The platinum group elements associated with the chromite ore was sulfide, arsenic, or sulfur arsenide state, you can use the flotation recovery. Olivine and serpentine in the chrome ore, we can consider to recovery, for the production of refractories, calcium magnesium phosphate, or diabase use.
