Resumen de IM 2012 Round-ups: Frac sand
More than 40% of the US's frac sand tonnage was used as hydraulic fracturing sand and well-packing and cementing sand, while 26% was used as glassmaking sand, 11% as foundry sand, 6% as other whole-grain silica, 6% as whole-grain fillers and building products and 10% for other uses according to the US Geological Survey (USGS).
The Maryland-based company, which is the second-largest US producer of silica sand, produced 1.78m tonnes in Q2 2012, of which 685,000 tonnes went to oil and gas markets, while 1.098m went to traditional silica sand users, such as glass makers.
IM reported in August that the Canadian National Railway had signed an agreement to haul frac sand from Superior Silica Sand's new 2.4m tpa frac sand storage facility in Wisconsin, US.
