Silica Sand Refractory Silica

Silica sand is a product of mechanical and chemical weathering of quartz-bearing igneous and metamorphic rocks such as granites and chemical weathering breaking down the less stable minerals such as feldspars and releases the more stable ones such as quartz and zircon. The stable mineral fragments are transported and re-deposited in water.
