Jul 31, 2011· Little study on silica effects. While all types of silica sand in Wisconsin produce airborne particles, the freshly fractured silica that comes from mining operations can be particularly dangerous, at least in a workplace setting, says Pierce, the UWEau Claire professor.
The washing process makes the industrial sand clean and ready for use. The source of most industrial sand mined in Wisconsin is sandstone, which is 95% to 99% sand and 1% to 5% very fine particles (silt and clay). Users of industrial sand require a clean grain of sand, without any fines or impurities. After mining, sand is rinsed or "washed ...

The sand grains themselves are harmless think sand on a beach but the silica dust particles created by the sand processing are basically tiny glass shards. Exposure to silica dust can cause silicosis, a potentially fatal lung disease. There are federal limits on acceptable silica exposure in the workplace, and some workers use respirators.
Sep 25, 2014· Analyzing estimated silica levels near frac sand sites. In January 2013, a research group from the University of WisconsinEau Claire did a study of particle pollution near sand mining and processing operations.
