    11/05/2015· Silica sand mining has minimal environmental impact, involves virtually no public health risk, and is an important part of domestic energy production that has substantial economic benefits. Heartland Policy Study No. 137, “Environmental Impacts of Industrial Silica Sand (Frac Sand) Mining,” documents the following facts:

  • Silicon The Environmental Literacy Council

    The major environmental impacts associated with silicon derive from its mining. Carbon monoxide is a byproduct of the basic process whereby silicon is prepared from silicon dioxide, but this is a negligible source of atmospheric carbon, compared to the amount generated by combustion of fossil fuels. Those who work in quarries and in the cutting of stone are at risk of silicosis, a lung disease

  • Silica Mining Processing Equipment Flow Chart Cases

    Silica Mining. In almost all cases, silica mining uses open pit or dredging mining methods with standard mining equipment. Except for temporarily disturbing the immediate area while mining operations are active, sand and gravel mining usually has limited environmental impact.

  • Silica Can Be an Environmental and Health Threat

    On our sister blog, Analyzing Metals, we discussed how working in the metal foundries industry can be a threat to one’s health because of exposure to silica dust known as respirable crystalline silica (RCS). Inhaling RCS can lead to silicosis, lung cancer, chronic obstructive pulmonary disease, and kidney disease. These dusts are produced by casting sand, fettlings and kiln linings.
