Silica sand is an industrial term used for sand or easily disaggregated sandstone with a very high percentage of quartz (silica) grains. Natural silica (silicon dioxide-SiO2) stone, quartz (lumps) is a simple compound of the elements silicon and oxygen. It is the most abundant mineral on the earth and is also one of the most important minerals on the earth. Industrial uses of silica depend on purity and physical characteristics. Some of the applications are: electronics, glass,
paint fillers, asphaltic concrete and general construction, water filtration, sand blasting, fillers for plastic and tire industries, refractory for glass and steel industries, epoxy grouting and foundry moulding sand and etc.
