Introduction to quartz sand

Quartz sand is a quartz particle obtained by crushing quartz stone. Quartz rock, also known as silica, is a hard, wear-resistant, chemically stable silicate mineral. Quartz sandstone, quartzite and vein quartz exist in nature. Quartz sandstone is a consolidated clastic rock with a quartz crumb content of over 95%.

Refined quartz sand is derived from various magmatic rocks, sedimentary rocks and metamorphic rocks, with less heavy minerals and associated minerals such as feldspar, mica and clay minerals. Quartzite is divided into two types: sedimentary genesis and metamorphic genesis. The former has no obvious boundary between clastic particles and cement. The latter refers to quartzite ore with deep metamorphism and pure quality. The vein quartz is formed by the action of hydrothermal fluid, almost entirely composed of quartz, and has a dense block structure.

The mineral content in quartz sand varies greatly, mainly quartz, followed by feldspar, mica, cuttings, heavy minerals, clay minerals and so on.

Physical and chemical properties

Quartz sand is a hard, wear-resistant, chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white, or colorless and translucent. Its hardness is 7. It is brittle and has no cleavage. Fracture, grease gloss, density 2.65, bulk density (1.60 for 1-20 mesh), 1.5 for 200-200 mesh, chemical, thermal and mechanical properties with obvious anisotropy, insoluble in acid, slightly soluble in KOH Solution, melting point 1750 ° C.

The main specifications of quartz sand:

Common specifications for quartz sand are: 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80 mesh, 100-120 mesh.
