Silicosis and Crystalline Silica Exposure and Mining ...

People who work in mining may breathe in tiny bits of silica, and eventually, develop a serious lung disease called silicosis. There is no cure for silicosis. Lung damage from silicosis is permanent, but with proper precautions it is preventable. Silicosis usually develops after years of exposure to low levels of silica.

Sand mining - Wikipedia

Sand mining is the extraction of sand, mainly through an open pit (or sand pit) but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete. It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface. Sand can replace eroded coastline. Some uses require higher purity than others; for example sand used in concrete must be free of seashell fragments.

Silica Minerals Education Coalition

Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
