Barite is the most common mineral of earthworms and its composition is barium sulfate. Produced in the epithermal veins, such as quartz - vein barite, fluorite - barite mai, often with galena, sphalerite, yellow copper ore, cinnabar symbiotic. Due to the large specific gravity of the barite, the beneficiation treatment is usually carried out by using the difference in specific gravity between the barite and the gangue. This step is called gravity separation of barite. In this article, we will introduce you to the barite beneficiation process.
The re-election method for barite has the advantages of large particle size, wide grain size and large ore processing capacity, and the re-election method plays a major role in the field of barite beneficiation. The re-election method is used to purify and process barite ore. It has the advantages of high efficiency, energy saving and environmental protection. It can also obtain ideal beneficiation index. It has excellent effect on the recovery and treatment of coarse and fine grain barite. In the barite concentrator, the re-election method has become the core method.
The process of barite beneficiation is mainly as follows: the barite ore is washed and sieved, crushed, graded and demineralized, and then the jigging beneficiation process can obtain fine concentrate with good quality, and the product grade can reach over 88%. The crushing of barite is generally carried out by a jaw crusher or an impact crusher, and the fine crushing is generally carried out by a roller crusher. At the same time, the selection can also be used for heavy medium drum sorting machine, cone classifier, shaker, screw machine, etc. The barite inlay has a particle size greater than 2 mm, and can usually be sorted by a heavy medium and jigging. The maximum particle size for heavy media sorting is 50 mm. The maximum particle size of wet and dry jigging is about 20mm. The inlay size is less than 2 mm and can be sorted by a shaker or a spiral classifier. Before the selection, a hydrocyclone should be used to remove the mud to improve the sorting effect. The jig can effectively select the coarse, medium and fine-grain barite ore, and the ore dressing effect is ideal, which can effectively increase the specific gravity of the barite and utilize the circulating water operation. The beneficiation process does not require the use of chemicals, and does not pollute the environment. It is a new type of high-efficiency, energy-saving and environmentally friendly barite beneficiation method.
At present, barite in China is generally used as a white Pigment (commonly known as lithopone), and is also used in chemical, paper, textile fillers, as a flux in glass production to increase the brightness of glass. But the most important thing is to use it as a weighting agent in the drilling industry and to refine it.
