Silicon Dioxide is a natural compound of silicon and oxygen found mostly in sand, Silica has three main crystalline varieties: quartz, tridymite, and cristobalite. Fine particulate silica dust from quartz rock causes over a longterm progressive lung injury, silicosis.
Sand and Gravel Mining Industry. When rocks erode out of the Rocky Mountains and are carried downstream by streams and rivers, they break apart making sand and gravel. The sand and gravel settles out of the water and form the river bed. As the river channel moves across the landscape, the sand and gravel (aggregate) deposits are left behind.
