Copper Smelting Quartz Sand, Grade : Common

Quartz sand is quartz quartz stone crushing processed.Quartz rock also known as silica, is a kind of hard texture, abrasion resistance, stable chemical properties of silicate minerals.In nature, quartz sandstone, quartzite and vein quartz exist.Quartz sand stone is a consolidated clastic rock, quartz clastic content of more than 95%, derived from a variety of magmatic rocks, sedimentary rocks and metamorphic rocks, less heavy minerals, associated minerals are feldspar, mica and clay minerals.
Physicochemical properties of refined quartz sand
Quartz sand is a hard, wear resistant, chemically stable silicate mineral.The main mineral composition of quartz sand is SiO2, quartz sand color is milky white or colorless and translucent, 7 hardness, brittle cleavage, conchatus fracture, oil sheen, density 2.65, bulk density (1-20 = 1.6), 20-200 1.5.Quartz sand chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750�.
Main specifications of quartz sand:
