How Clay Is Removed From Silica Sand

Occupational Cancer Risk Series SILICA DUST.

Crystalline silica is found in stone, rock, sand, gravel and clay, as well as products such as bricks, tiles, concrete, artificial stone benchtops and some plastic materials (Figure 1). When these materials are worked on, the silica is released as a fine dust. This dust is respirable crystalline silica (commonly called silica dust).
