The sedimentary rocks are sedimentary rock composed of siliceous minerals. Silica is dark gray with a light tint of blue. Most commonly found in combination with feldspar and quartz. Silica is found in association with oxygen as Sio 4 silicate ion, it founds in silica rich rocks such as sandstone, granite, obsidian. Silica is second most ...
Rock quarries create invisible dust particles proven to cause silicosis—an incurable lung disease. Longterm exposure to particulate matter dust is strongly associated with heart disease, stroke, infertility, and pregnancy complications. Affecting Comal County communities of .
It can be released into the air when the rock or articles made from the rock are crushed, cut, or worked in some other way. It is the fine fraction of the dust, the respirable fraction, that is harmful to health when inhaled. Respirable crystalline silica is often abbreviated as RCS.

Mar 13, 2011· Freshly fractured silica dust appears to be more reactive and more hazardous than old or stale dust. This may be a consequence of a relatively higher surface charge on freshly formed particles. The most common processes that produce respirable silica dust in mining and quarrying are drilling, blasting and cutting silicacontaining rock.
