Types of Silica Sand Different Kind of Quartz Sand

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.
