Silica Sand. Silica sand, also known as silica or quartz sand, is a kind of hard, wear-resistant and chemical stable silicate mineral. Its main mineral composition is SiO2. According to different mining and processing methods, silica sand can be divided into artificial silica sand, water washed sand, scrubbed sand, selected (flotation) sand, etc.

Such sand deposits are said to be mature because other rock-forming minerals are already broken down by the weathering process leaving only the super-resistant quartz as a residue. Silica sand is a mineral resource. It is mined mostly for glass-making. Another major use of sand is a concrete production but that does not need sand to be as pure.
