Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules. Silica sand deposits are most commonly surface-mined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities.
