( 1 ) Processing method of mineral processing      Quartz, feldspar, mica, iron minerals, titanium minerals and other non-clay minerals and organic matter in the separated kaolin, produced to meet various needs in the area of industrial kaolin products, in addition to re-election, flotation, magnetic separation of kaolin In addition to purification, the kaolin is sometimes treated by deep processing methods such as chemical bleaching, ultrafine stripping, calcination, and surface modification.           Hydraulic classification includes spiral classification ( separation +       2. HGMS       The magnetic field strength of 1 600 kA/m or more is generated by using a magnetic magnetic medium to remove Fe 2 O 3 and TiO 2 in kaolin, and a papermaking paint and a high-grade ceramic raw material are produced.        3. Selective flocculation          Adding bleaching agent such as insurance powder to reduce the high-valent iron of limonite and hematite in kaolin to soluble ferrous iron, or adding oxidizing agent to oxidize pyrite and dyeing impurities to improve the whiteness of kaolin.       5. Stripping          6. calcined         7. The surface-modified       The kaolin is coated with a coupling agent or the like to increase the amount of the kaolin added to the plastic rubber, and is used for treating a kaolin filler for rubber plastics.  ( 2 ) Work art flow Cheng       The ore processing of kaolin is divided into two processes: dry process and wet process.      The dry method generally breaks the produced ore through the crusher to      The wet processing process includes several stages of dispersing, grading, impurity sorting and product processing of the mud. The general principle process is: raw ore → crushing → slurry → sand removal → cyclone classification → stripping → centrifuge classification → magnetic separation ( or bleaching ) → concentration → pressure filtration → drying → ceramic grade or paper coating grade products.      The general principle flow of coal-based ( hard ) kaolin processing is: raw ore → crushing → slurry → cyclone classification → stripping → centrifugal classification → concentration → pressure filtration → internal steam drying → calcination → depolymerization → filler grade or paper coating Grade kaolin.  ( 3 ) Selection mine real Practice  1. China Kaolin Mountain View Concentrator      Guanshan Concentrator has a designed production capacity of 50 000t per year and the largest grain size of the ore.

     1. hydraulic classification
     By adding a flocculant, impurities such as fine-grained quartz, pyrite, and alumite are selectively separated to produce a knife-coated grade kaolin. Common flocculant hexametaphosphate, sodium phosphate, ammonium polyacrylamide, water glass.
     4. chemical bleaching
     Stripping with stirring, a fine media mill grinding stripping ball in effect, kaolin particles are separated into an aggregate of crystal flakes, production size of less than 2 μ m content of more than 90% of the blade coating grade kaolin.
