Silica sand is a naturally occurring granular material composed of high levels of silica (silicon dioxide, SiO2). It’s abundance, purity, and diverse range of applications make it a valuable and sought-after resource in a wide variety of markets such as glass, ceramics, coatings, metals, foundry, polymers, sports and recreation, oil and gas, construction, water filtration and many more.
Our silica sand is as high as 99.65% quartz. It is hard, chemically inert, and has a high melting point of 3,115° F (1,713° C), making it ideal for various applications.
We mine and process our silica sand as both whole and ground silica, and we offer our silica sand products in various ways:
Dry or damp
Coated
Ultra fine to coarse
Calcined
Screened
Micronized
Colored
Milled
Washing, classifying and desliming process
The grade of SiO2 in the quartz stone is reduced with the thinner of quartz grain size, while the grade of mineral impurities (such as iron and aluminum impurities) is increased, this kind of phenomenon is especially obvious in the quartz stone containing a lot of the clay minerals. Therefore, the spiral washing machine, drum sieve, hydrocyclone, desliming bucket and hydraulic classifier are often used to the water concentration of quartz stone, it is very necessary to carry out the classification and desliming in the quartz processing plant. As a pretreatment method before the ore separation, the washing, classifying and desliming are applied earlier and widely in the quartz washing plant, but this quartz mineral process doesn't have the obvious removal effect for the thin-film iron and adhesive impurity minerals on the surface of quartz stone.
