Chromium Ore Gravity Separation and Flotation Process

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 separation+flotation process

After crushing and grinding the raw ore, gravity separation is carried out first to separate some coarse concentrate, and the tailings are further flotation after gravity separation.
