Barite Beneficiation Process

Barite ore can be categorized into four types based on its properties: sedimentary, volcanic sedimentary, hydrothermal, and residual slope accumulation. Each type requires different barite beneficiation methods and equipment.

Hand selection is commonly used for purer barite ore or to obtain barite concentrate through ore washing.

Gravity separation is suitable for residual barite ore with a relatively simple composition and coarse particle size. It is often found in association with minerals such as galena, sphalerite, chalcopyrite, and cinnabar. Separation equipment like jigs and shaking tables are used in this process.

Flotation separation takes advantage of the buoyancy of hydrothermal barite, which has a specific affinity for the flotation process. It is effective for removing gangue minerals like sulfide and fluorite that are associated with barite. This method is suitable for treating ores with a finer particle size.

Magnetic separation is utilized to remove iron-containing minerals from barite ore, particularly those associated with minerals like siderite. The magnetic differences between barite and iron-bearing minerals are used for sorting. Magnetic separation is often combined with gravity separation.

In cases of barite composite ore with complex associated minerals or sedimentary barite ore with fine mineral distribution and low-grade raw ore but high-grade concentrate, a combination of gravity separation and flotation should be employed.

Barite Processing Plant

1. Barite Washing Plant
   Equipment configuration:

• Jaw crusher
• Log washer
• Spiral sand washer
• Vibrating screen
• Belt conveyors

1. The materials under the grizzly bar of the vibrating feeder (1) are conveyed to 2 spiral sand washers (2) through the material guide chute.
2. The material above the grizzly bar is fed to the jaw crusher (3). The discharged material of the jaw crusher enters the 2 spiral log washers (4), and the spiral out materials is fed into 1 spiral sand washer (5).
3. The overflow of the spiral ore washer is guided to the vibrating screen (6), and the discharging materials of the 3 spiral sand washers are all fed into the vibrating screen. The vibrating screen sieves out 2 kinds of finished products with different particle sizes, 0-20mm (7) and materials over 20mm (8).

2. Barite Gravity Separation

1. Crushing: Barite, being a brittle and fragile material, is crushed using a practical and straightforward jaw crusher in the first stage of crushing. The crushed material is then transported to a secondary fine jaw crusher for further crushing (2nd stage).
2. Screening: In order to meet the particle size requirements for jig separation, a screening process is necessary. This is achieved by using a circular vibrating screen to screen the crushed products (3rd stage).
3. Stock bin and feeder: The purpose of the stock bin is to ensure a consistent and stable supply of materials to the subsequent equipment, preventing sudden or uneven workload. The vibrating feeder is responsible for uniformly and steadily feeding the materials to the jig concentrator (4th stage).
4. Gravity separation: The crushed products are divided into different particle sizes and directed into the jig concentrator for gravity separation, where the separation of barite takes place (5th stage).
5. Dewatering stage: To meet specific requirements, a suitable mechanical dehydration process is designed to remove excess moisture from the separated products (6th stage).
