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 ...
The processing of metals at elevated temperatures, usually by induction heating in high vacuum.
Industry:Mining
The product from an anthracite coal-preparation plant, usually below 1/8 in (3.2 mm).
Industry:Mining
The product of a basic open-hearth furnace refined to a point where the impurities are reduced to the lowest practicable minimum, after which copper and molybdenum are added in correct proportions.
Industry:Mining
The product of a mine, or of a beneficiating or agglomerating plant, which is shipped without further processing to the consumer.
Industry:Mining
The product of a procedure that corrects the distortions in aerial photography due to the instability of the camera platform, the terrain relief, and the angle of the light rays entering the camera lens. The ortho instrumentation attached to a stereo plotting instrument rectifies the image in a transfer process so as to reposition it in its correct planar position.
Industry:Mining
The product resulting from the artificial crushing of gravel with substantially all fragments having at least one face resulting from fracture.
Industry:Mining
The production of a chemical compound by the union of elements or of simpler compounds or by the degradation of a complex compound, esp. by laboratory or industrial methods.
Industry:Mining
The production of a double layer of charge at a mineral interface, or production of changes in double-layer density of charge, brought about by application of an electric or magnetic field (induced electrical or magnetic polarization). Induced electrical polarization is manifested either by a decay of voltage in the Earth following the cessation of an excitation current pulse, or by a frequency dependence of the apparent resistivity of the Earth. Abbrev: IP.
Industry:Mining
The production of shot by pouring molten metal in finely divided streams. Solidified spherical particles are formed during descent and are cooled in a tank of water.
