Chromite Gravity and Magnetic Separation 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+magnetic separation process

After crushing and grinding the ore, gravity separation is first used to obtain some concentrate products, and the tailings from gravity separation are further recovered with magnetic separation method for useful minerals.

Process characteristics

High grade concentrate.

Typical beneficiation plant

The Don River beneficiation plant in the Nankenpilsa mining area of Kazakhstan adopts a gravity magnetic separation process. The gravity separation method includes heavy medium beneficiation, jigging beneficiation, shaking table and spiral beneficiation machine, and the fine mud is separated by magnetic separation. The specific process is as follows:
