Silica Sands

Silica sand is one of the most common varieties of sand found in the world. It is used for a wide range of applications, the main uses of Silica Sand are in the manufacture of glass and a host of specialist applications within the construction industry.

High grade silica sand is usually found as unconsolidated deposits below thin layers of soil and overburden. After quarrying, the sand often undergoes considerable processing before sale. The processing may include washing and cleaning of the grains, sizing to remove coarse and very fine fractions, and physical and chemical processes to remove iron, chromium and other deleterious minerals. After processing, the sand may be dried and some applications require it to be ground in ball mills to produce very fine material.

DUO has supplied processing equipment to specialist Silica Sand producers such as WBB Minerals and Garside Sands.
