Company Profile:
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 ...
In electrolytic refining of metals, tanks in which the electrolytic solution is reconstituted.
Industry:Mining
In experimental work with cylinders, a compression applied parallel with the cylinder axis. It should be used in an appropriate sense only in the interpretation of deformed rocks.
Industry:Mining
In exploration geochemistry, principally zinc, copper, cobalt, and lead, but under special conditions including one or more of the following metals: bismuth, cadmium, gold, indium, iron, manganese, mercury, nickel, palladium, platinum, silver, thallium, and tin.
Industry:Mining
In explosion-formed crater nomenclature, the remote zone that undergoes no measurable permanent deformation.
Industry:Mining
In explosion-formed-crater nomenclature, this zone differs from the rupture zone by having less fracturing and only small permanent deformations. There is no distinct boundary between the rupture and plastic zones.
Industry:Mining
In explosion-tested equipment, housings for electric parts are designed to withstand internal explosions of methane-air mixtures without causing ignition of such mixtures that surround the housings.
Industry:Mining
In explosives casting, large amounts of low-cost ammonium nitrate mixtures are loaded into medium-sized drill holes in a usual ratio of more than 1 lb of powder per cubic yard (0.59 kg/m<sub>3</sub>) of overburden. The explosive charges are detonated through milliseconddelay electric blasting caps. When the shot is fired, a large part of the overburden is blasted into the pit away from the high wall and up on the spoil pile where it attains a favorable angle of repose.
Industry:Mining
In fault descriptions, the displacement of one block relative to the other, rather than to some fixed point or plane of reference.
Industry:Mining
In faulting, the distance between the two parts of a disrupted unit (e.g., bed, vein, or dike), measured in any specified horizontal direction. Compare: vertical separation
Industry:Mining
In filtering system, use of a loop more than 30 ft (9.1 m) high between receiving vessel and vacuum pump, to protect latter against carryover of liquid.
