Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are
Why is Silica Hazardous? Silica, often referred to as quartz, is a very common mineral. It is found in many materials common on construction and oil gas sites, including soil, sand, concrete, masonry, rock, granite, and landscaping materials.
Sep 25, 2014· Mining, processing and transporting sand generate large quantities of silica dust, which is notorious for the damage it does to the lungs and respiratory system when inhaled. In recent years, the dramatic expansion of hydraulic fracturing and horizontal drilling technology to extract gas and oil, commonly called "fracking," has led to boom in sand mining across the upper Midwest, creating a ...

Ionizing radiation is a hazard in the mining industry. Radon can be liberated from stone while it is loosened by blasting, but it may also enter a mine through underground streams. It is a gas and therefore it is airborne. Radon and its decay products emit ionizing radiation, some of which have enough energy to produce cancer cells in the lung.
Because of the abundance of silica, potential hazards are widespread. NIOSH in the US has estimated that million workers in the USA are exposed to silica dust. Industries affected are quarrying, mining, steel, iron, metal foundries, abrasive blasting, construction, glass and ceramics, paint and pigments, granite and stone industries.
