What is Silica Sand? Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). Silica sand deposits are most commonly surface-mined in open pit operations, but dredging and underground mining are also employed….

Purification starts by heating the sand with a reducing agent, carbon, to produce carbon monoxide and silicon. The product of this process, known as metallurgical grade silicon (MG-Si), may be as much as 99% pure. Additional processing is completed until ultrapure electronic grade silicon (EG-Si) is obtained. In addition to being very pure, …
