The Lingshou Yijia Mining Co., Ltd. specializing in the production of quartz sand, quartz sand is a non-metallic minerals, is a hard, wear-resistant, stable chemical properties of silicate minerals, and its main mineral component of SiO2, quartz sand The color is milky white, or colorless translucent shape, hardness, quartz sand is an important industrial mineral raw materials, non-hazardous chemicals, widely used in the glass, foundry, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction chemicals, plastics, rubber, abrasive industry. 
 The quartz sand is quartz stone crushing processing from the quartz grains. 
 Refined quartz sand 
 Quartz stone (quartz rock), also known as silica, is a hard texture, abrasion resistance, and chemical properties of silicate minerals. Quartz sandstone, quartzite and quartz exists in nature. The quartz sandstone is the consolidation of clastic rocks, quartz debris content of 95% or more, from a variety of igneous rocks, sedimentary, and metamorphic, less heavy minerals, associated minerals as feldspar, mica and clay minerals. Quartzite points two kinds of sedimentary origin and metamorphic origin, the former boundaries of the detrital grains and cement is not obvious, the latter refers to the degree of metamorphism of deep, pure quality quartzite ore. Quartz veins formed by hydrothermal, almost entirely composed of quartz and compact block structure. 
 Mineral content in the quartz sand dominated by quartz, followed by feldspar, mica, debris, heavy minerals, clay minerals. 
 Physical and Chemical Properties 
 Quartz sand is a hard, wear-resistant, stable chemical properties of silicate minerals, and its main mineral component of SiO2, quartz sand color is milky white, or colorless translucent like hardness is brittle without cleavage, shell like fracture, oil sheen, density of 2.65, bulk density (1-20 mesh, 1.6), 20 200 mesh 1.5, its chemical, thermal and mechanical properties have obvious anisotropy, do not dissolve in acid, slightly soluble in KOH solution, the melting point of 1750 ℃. 
 The main specifications of the quartz sand: 
 Common Specifications of quartz sand 1-2mm ,2-4mm ,4-8mm, 8-16mm, 16-32mm ,10-20 mesh ,20-40 mesh ,40-80 mesh, 100 - 120 mesh, 200 mesh, 325 Head 
 Applications 
 Quartz sand with unique physical and chemical properties, making it occupies a pivotal position in the aviation, aerospace, electronic, mechanical as well as the rapid development of IT industry, especially its intrinsic molecular chain structure, crystal shape and the variation of lattice it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion resistance, the piezoelectric effect, resonance effect, as well as its unique optical properties, play an increasingly important role in many high-tech products. 
 The quartz sand is an important industrial mineral raw materials, non-hazardous chemicals, widely used in the glass, foundry, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber,
