A1562 Silica dust levels in an a open-pit coal mine - Confex - American Diatomite, Inc.
Until recently, few understood the dangers created by crystalline silica dust. Unlike normal sand, crystalline silica dust has razor sharp edges and is microscopic in size. When inhaled, it bypasses the body's natural defenses and become permanently lodged in the deepest parts of the lungs. It has proven links to diseases that lead to death including silicosis, lung cancer, …Silica sand deposits are most often surface-mined in open pit operations but dredging and underground mining are also used. For industrial applications, deposits of silica yielding products of at least 95% quartz (SiO 2) are preferred.
