Supreme Court upholds Winona County's silica sand

Parts of southern Minnesota and western Wisconsin contain rich deposits of high-quality silica sand of the ideal size hardness and purity for hydraulic fracturing The sand acts as ball bearings to prop open cracks in underground rock to let oil and gas flow out

Standard sand cast Ni-hard will have a BHN of 550 to 650 For grit service where the maximum hardness of silica sand can exceed the minimum hardness of standard Ni-hard extra steps must be taken to push the Ni-hard BHN even higher This is achieved by modifying standard Ni-hard through a cryogenic process to increase both hardness and
