High purity raw materials are a prerequisite for the manufacture of high quality refractories. Natural mineral raw materials usually have lean ore and rich ore, uneven composition and large fluctuations in quality. Direct use of refractory materials will cause trouble to the production process and cause unstable quality. Some things may not even be used. Therefore, it needs to be enriched and classified by mineral processing. The role of mineral processing is:
(1) Separating useful minerals from ore from minerals and enriching useful minerals.
(2) Remove harmful impurities from minerals.
(3) Recover useful associated minerals as much as possible and make comprehensive use of mineral resources.
(4) The main methods for grinding ore or ore dressing products and classifying them into different specifications are flotation, magnetic separation, re-election, electric selection (electrostatic selection), photoelectric selection, hand selection, chemical beneficiation, friction and Eliminate beneficiation and beneficiation according to particle size, shape and hardness. The combination of beneficiation methods and various beneficiation methods for refractory raw materials depends on the physical properties of various minerals in the raw materials, such as particle size and shape, specific gravity, rolling friction and sliding friction, wettability, electromagnetic properties, Solubility, heating properties, etc. At present, the mineral processing methods commonly used for refractory raw materials are listed in the following table.
