What Is Silica Sand How Is It Different From

Silica sand is a commercial and consumer product that is widely available throughout North America. How silica sand is used depends on physical, chemical, and mechanical characteristics such as grain size, shape, colour, structure, and distribution, as well as refractoriness, strength and stability. These characteristics can differ depending on how the mineral is processed after it is mined.
