The chrome ore used in the industry is chromite, which is a general term for chromium-containing spinel minerals with higher chromium content.
1、Gravity separation: Gravity separation is an important method in the chrome ore beneficiation and the gravity separation method using loose stratification in the aqueous medium as the basic behavior is the main method for enriching chrome ore in the world.
2、Magnetic separation: chromite has weak magnetic properties, so it can be sorted by magnetic separator, subdivided to remove the strong magnetic minerals in the ore in a weak magnetic field or to separate gangue minerals in a strong magnetic field.
3、Electrification: Electrification is a method of separating chrome ore and silicate gangue minerals by the differences in mineral electrical properties such as electrical conductivity and dielectric constant.
4、Flotation: mainly used for the recovery of low-grade fine-grained chromite.
