benefits of frac sand mining as they pertain to air quality, water quantity, water quality, and reclaiming mines after mining is completed. In Part 2, the authors review the background and potential of industrial sand mining in the United States and put that potential in the context of supply and demand for silica sand, now and into the future.
Silica sand was milled by High Energy Milling in order to reduce the size into powder form. Effect of milling time shown the content of sodium and silicon is increased in sodium silicate solution obtained from various times of silica sand milling (30, 60 and 90 minutes, respectively) which is .

The silica sand is an assemblage of individual silica grains in the size range upto 2 mm. Sand can be formed in nature by natural weathering of sandstone and quartzite or mechanically by crushing a sandstone /quartzite or by a process of flotation whereby the various constituents in a pegmatite or kaolin mixture are separated.
