PTMS magnetic separation

what is magnetic separation in Quartz？

Quartz has high fire resistance. Industrially, quartz sand is often divided into: ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused silica sand and silicon micro-powder.

Ordinary quartz sand

Ordinary quartz sand, namely SiO2 ≥ 90-99%, Fe2O3 ≤ 0.06-0.02%, refractoriness 1750 ° C, appearance: yellow granules on the surface of some large particles. Ordinary quartz sand is generally a kind of water treatment filter material which is made of natural quartz ore, crushed, washed, dried and secondaryly screened; the filter material has: no impurities, no angularity, high density, high mechanical strength, and The long life cycle of the dirt line is an ideal material for chemical water treatment. The particle size range is 5-220 mesh, which can be produced according to the user's requirements. Main uses: metallurgy, ink silicon carbide, glass and glass products, enamel, cast steel, water filtration, wood particle, chemical, spray and other industries.

Refined quartz sand

Also known as pickled quartz sand, SiO2 ≥ 99-99.5%, Fe2O3 ≤ 0.005%, using high-quality natural quartz sand, mortar.

High purity quartz sand

SiO2 ≥ 99.5 - 99.9%, Fe2O3 ≤ 0.001%, using high-quality natural quartz stone, mortar. (mm is glutinous rice)

Fused silica sand

Chemical composition: SiO2 99.9-99.95%, Fe2O3 5PPM-25PPM max, Li2O 1-2PPM max, Al2O3 20-30PPM max,

K2O 20-25PPM max, Na2O 10-20PPM max (PPM is in parts per million).

Physical properties:
