Silica Sand

Quartz sand is processed by crushing quartz grains of quartz, quartz stone is a non-metallic minerals, is a hard, stable wear and chemical properties of silicate minerals, the main mineral component of SiO2, quartz sand The color is white or colorless, translucent, Mohs hardness of 7, quartz sand is an important industrial mineral raw materials, non-hazardous chemicals, widely used in glass, foundry, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasive, media and other industries.

Ordinary quartz sand, which SiO2≥90-99% Fe2O3≤0.06-0.02%, refractoriness 1750 ℃, the appearance of some large particles, the surface of yellow cysts. Ordinary quartz sand is generally made from natural quartz ore, by crushing, washing, drying, secondary screening of a water treatment filter; the filter has: no impurities, no school angle, high density, high mechanical strength, pollution load capacity of the line using a long period, is the ideal material for chemical water treatment. Size range 5-220, user requirements particle production. Main purpose: metallurgy, Mexico silicon carbide, glass and glass products, ceramic, steel, water filtration, sodium silicate, chemicals, spraying noisy industries.

Refining quartz sand, quartz sand, also known as pickling, 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 for millimeters)
