The main chromite ore processing method is gravity separation. Shaking table and jig machine are often used in production. Sometimes the grade and ferrochrome ratio of chrome concentrate can be further improved by weak magnetic separation or strong magnetic separation after gravity separation.

Chrome spinel with higher iron content or ore with dense symbiosis with magnetite, in the concentrate obtained after ore processing, chrome grade and chromite ratio are low, can be considered as an ingredient for pyrometallurgical production of chromite, or hydrometallurgical treatment. For example, sodium dichromate method, chromium hydroxide method, reduction corrosion method, chlorinated roasting acid leaching or electrolysis method. It has been practiced to treat low-grade chromite concentrate by hydrometallurgy.

The associated platinum group elements in chromite, such as sulfide, arsenide or sulfur arsenide, can be recovered by flotation. Olivine and serpentine in the ore can be comprehensively recovered for the production of refractory materials, calcium magnesium phosphate fertilizer or diabase cast stone.
