Gravity beneficiation process for chromium ore

Gravity beneficiation process for chromium ore

At present, more than 50 types of chromium containing minerals have been discovered in nature, belonging to the categories of oxides, chromates, and silicates; Chromite is currently the only mineral in industrial production, mainly composed of iron magnesium chromite, magnesium iron chromite, aluminum iron magnesium chromite, etc. The selectivity of chromite mainly depends on its grade, embedded particle size, and gangue composition. Currently, mineral processing methods include gravity separation, magnetic separation, electrical separation, flotation, roasting magnetic separation, etc.

Gravity beneficiation process: Gravity beneficiation plays an important role in chromium ore beneficiation and is currently the main method for chromium beneficiation worldwide; After crushing and grinding, the raw ore is sorted using gravity separation methods such as jigging, chute, heavy medium beneficiation, and shaking table.

Process characteristics: simple process, mature equipment, and environmentally friendly.

Typical beneficiation plant

The beneficiation process of the Rustenburg Priti Chromium Mine in South Africa is as follows:
