Quartz sand is the quartz writing processing of silica particles. Also known as silica, quartz, quartz rock) is a texture hard, wearresisting, stable chemical properties of silicate minerals. In nature exist in quartz sandstone, quartzite and vein quartz. Quartz sandstone is consolidation of clastic rocks, quartz particles content more than 95%,From all kinds of magmatic rocks, sedimentary rocks and metamorphic rocks, heavy minerals is less, associated minerals as feldspar, mica and clay minerals content.Quartzite sedimentary origin and metamorphism, the boundaries of the former clastic particles and cement is not obvious, which is a deep metamorphic grade, quality, and the pure quartz ore.Vein quartz is formed by hydrothermal process, almost all is composed of quartz, dense block structure.
