Beneficiation and purification of refractory raw materials

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) Grinding ore or mineral processing products and classifying them into products of different specifications

The main methods of mineral processing include flotation, magnetic separation, re-election, electric selection (electrostatic selection), photoelectric selection, hand selection, chemical beneficiation, friction and elimination of beneficiation, and beneficiation by 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.
