The U.S. Bureau of Mines (USBM) was the primary United States Government agency conducting scientific research and disseminating information on the extraction, processing, use, and conservation of mineral resources.
Founded on May 16, 1910, through the Organic Act (Public Law 179), USBM's missions ...
Composed of detrital crystalline grains little worn and solidly compacted by siliceous or other mineral matrix, so as to resemble a true crystalline rock.
Industry:Mining
Composed of sharp, solid quartz grains and used as abrasive for sawing stone; usually ungraded and about equivalent to a No. 1 sandblasting sand.
Industry:Mining
Composed partly or wholly of halite; esp. said of a sedimentary rock containing halite as cementing material, such as halitic sandstone.
Industry:Mining
Compounds of carbon with iron and other elements in steel; e.g., Fe<sub>3</sub>C (cementite), Fe<sub>4</sub>W<sub>2</sub>C , and Cr<sub>4</sub>C<sub>2</sub>.
Industry:Mining
Compressed-air drill that traps and removes drilling dust instead of sludging it with added water.
Industry:Mining
Compressed-air drill worked by reciprocating piston, hammer action, or turbo drive.
Industry:Mining
Compression in which no heat is added to or subtracted from the air and the internal energy of the air is increased by an amount equivalent to the external work done on the air. The increase in temperature of the air during adiabatic compression tends to increase the pressure on account of the decrease in volume alone; therefore, the pressure during adiabatic compression rises faster than the volume diminishes.
