Silica Sand

Hard rock such as quartzite and hard minerals such as quartz, flint, chert etc. had been commonly used by man in Palaeolithic Age as weapons. Of all the non-metallic minerals, silica sand had the most diversified use. Silica bearing rocks and minerals such as quartz, quartzite, silica sand together with other varieties of silica like agate, amethyst, jasper, flint etc. are used in a host of industries such as glass, ceramics, foundries, ferro-alloys, abrasives, refractories, ornamentation etc.

The uses of silica sand depend on its mineralogy, chemistry and physical properties. It is mainly used for making glass and glass fibre, silicon carbide, sodium silicate, portland cement, silicon alloys and metals filter media in water treatment, sandpaper and also for foundry sand, hydraulic fracturing, sand blasting, paint and a host for other applications.

Ashapura silica sand resources are from both mining and by product generated from kaolin washing. Impurities are taken care by multiple stage washing followed by attrition scrubbing, magnetic separation and spiral classifier. Ferrous impurities are removed to assure best possible purity of silica sand for all the applications. Ashapura also has mechanical drying facility to address the drawbacks of natural drying considering the volume demand.
