The technical characteristics of kaolin mineral processing plants in various countries around the world are as follows:

① The raw ore extracted from the mine undergoes on-site rough selection, discarding a lot of industrial waste residue for mining. This not only solves the problem of filling the empty area, but also reduces the use and transportation of raw ore boxes in the mining plant. Only the optimal selection plant is established, and the titanium concentrate of each rough selection plant is centrally selected;

② Pipeline transportation is generally used between mining and optimization plants. In the United States, kaolin coal slurry has been transported through pipelines since 1939;

③ For paper making with high concentration, thickeners are added to the coal slurry throughout the screening process, and coagulants are added throughout the dehydration process. Diaphragm pressure filters or filter products are sold as products without drying;

④ In addition to Hydrocyclone classification, the concentrator also uses centrifugal separator, ball mill, high gradient direction dry magnetic separator and flotation machine to improve product particle size and reduce iron, titanium, sulfur and other residues;

⑤ The organic chemical bleaching agent processing technology is widely used in key kaolin producing countries such as the United States, the United States, and the former Soviet Union to produce high fineness kaolin products, but its cost is relatively high;

⑥ Gaolingshang products are sold in small, coarse powder, fine powder, and thick forms. Manufacturers supply different products according to customer regulations. There are many types of drying equipment for products, but spray dryers are widely used, because their costs are relatively low;

⑦ Mining plants not only produce a large amount of products, but also have a variety of standardized products. Must meet the needs of different customers. There are four major categories and 34 types of products produced by kaolin enterprises in China. This product is widely used as filler and building coating for printing paper, raw materials for ceramic technology, filler and synergist for vulcanized rubber and plastic, ingredients for cement felt paper, flat roof building coating and waterproof coating, ingredients for glass fiber, printing ink color paste, filler for skin care products and soap, media for chemical fertilizer and Manure, adhesives for polishing materials, carbon molecular sieve generation, crude oil metal catalyst, Nuclear reactors and many other fields.
