Material introduction

Barite is brittle and brittle, and the crystals are large tubular. For the separation of barite, Xinhai's general beneficiation methods include gravity separation, magnetic separation and flotation.

Processing of high-brightness fine powder and ultra-fine powder High-brightness finely pulverized barite powder is obtained by pulverizing, washing and whitening barite ore. Production of barium salt products such as lithopone (zinc barium white), barium chloride, barium hydroxide, etc.


crushing and screening

The crushing process adopts a jaw crusher, which uses a two-stage crushing process to crush the mined large barite; the screening process adopts a circular vibrating screen with large processing capacity, high screening efficiency, simple and practical, and the failure rate of this type of vibrating screen is Low, large processing capacity, high screening efficiency and easy to operate, it is an ideal equipment for barite screening. Perform jig sorting.


For the barite gravity beneficiation process, the usual practice is to crush and screen. After the jig beneficiation process, a concentrate with a higher grade can be obtained, and the product grade can reach more than 80%. Jig is used as the main equipment for barite ore sorting and purification. It has the characteristics of energy saving, high efficiency and environmental protection, and has high economic benefits.

magnetic separation

Wet magnetic separators are usually used to select some iron-bearing minerals such as siderite for barite raw materials that require barium-based pharmaceuticals with very low iron content.


Flotation is often used for the separation of barite ore with very fine embedded particle size and its gravity tailings. According to different adsorption methods, anionic collectors such as fatty acid alkyl sulfates and alkyl sulfonates or cationic amine collectors are used to flotate barite ore.


  • Advantage one

    1. According to the ore composition, you can freely choose the matching model.

  • Advantage two

    2. The whole system reduces energy consumption and improves recovery rate.

  • Advantage three

    3. Small footprint, convenient operation and higher beneficiation efficiency.

  • Advantage four

    4. The discharge material can reach the standard concentrate index, which is environmentally friendly and pollution-free.
