Silica, or silicon dioxide (SiO2), is the major constituent of commercial sands. Lesser amounts of feldspar, mica, iron oxides, and heavy minerals are common. Industrial sand, often called silica sand, and industrial gravel differ from construction sand and gravel in that they contain high percentages of quartz, or silica, typically 95 to 99

Overexposure to airborne respirable crystalline silica dust (referred to here as "silica dust") can cause silicosis, a serious and potentially fatal lung disease. Mining continues to have some of the highest incidences of worker-related silicosis, and the mining machine operator is the occupation most commonly associated with the disease [NIOSH 2003].

Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. The material may undergo primary crushing at the mine site before being transported to the processing plant. Figure 11.19.1-2 is a flow diagram for industrial sand and gravel processing.
