The production process of chromite sand
1.chromite sand raw materials (has been broken into powder) water washing processing, the purpose is to sieve the particle size of the drum to remove mud and impurities;
2.dry the raw materials to remove water;
3.Granularity;
4 to screen the granularity of the magnetic selection, the purpose of removing iron to remove silicon; the chromium content after magnetic selection reaches more than 46%, and silicon is below 1%; once it is removed, it is easy to dissolve in almost all inorganic acid In 4102, but insoluble. 5 packaging finished products.
