how to remove the impurities of barite ore

Barite ore

Barite is an important non-metallic mineral, the main component of which is barium sulfate.Barite is stable in chemical properties, insoluble in water and hydrochloric acid, non-magnetic and nontoxicity.Occurs in low-temperature hydrothermal veins, such as quartz - barite veins, fluorite - barite veins, often with galena, sphalerite, chalcopyrite, cinnabar and other symbiosis.

Barite purification methods

The physical purification methods of barite mainly include: hand pick, gravity separation and magnetic separation。The main basis of hand pick is the difference in the color and density of barite and associated minerals.After crushing, barite and gangue minerals can be effectively dissociated, and lumpy barite can be selected by hand.

Hand pick to remove the impurities of barite ore

Hand pick is simple,easy to operate，low dependence on equipments. But only can process some rich barite ore and low production efficiency,causing great waste of barite resouces.

Gravity separation to remove the impurities of barite ore

The gravity separation is carried out according to the density difference between barite and associated minerals. The raw ore is crushed and grinded to a certain grain grade and then entered into the gravity equipment for beneficiation so as to remove the gangue.

Magnetic separation to remove the impurities of barite ore

Magnetic separation is a method of separation under the action of magnetic force by taking advantage of the difference of magnetism between different ores. Magnetic separation is mainly used to remove some minerals with magnetic iron oxide, such as siderite, which is usually used in combination with gravity separation to reduce the content of iron in barite concentrate.

Gongyi Forui Machinery Factory is leading manufacturer of barite processing equipment in China,which accounts for 85% of China's domestic market share in barite beneficiation field. our machines are also delivered to Morocco,Brazil,Pakistan,etc and enjoyed good reputation.
