    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.

    How Silicon Is Made

    The Manufacturing Process The basic process heats silica and coke in a submerged electric arc furnace to high temperatures. High temperatures are required to produce a reaction where the oxygen is removed leaving behind silicon. This is known as a reduction process. In this process metal carbides usually form first at the lower temperatures.
