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 ...
A continuous record of wind speed and direction given by an anemograph.
Industry:Mining
A continuous ribbon or strip of steel, invar, dimensionally stable alloys, specially made cloth, or other suitable material, having a constant cross section and marked with linear graduations, used by surveyors in place of a chain for the measurement of lengths or distances.
Industry:Mining
A continuous screw-shaped steel joist lining for staple shafts. The lining is fixed to the ground by strata bolts rigidly fixed every 120 degrees without any yielding device. Developed in Germany and its use is claimed to effect considerable overall savings.
Industry:Mining
A continuous series of pockets, formed of a flexible material festooned between crossrods, carried by two endless chains or other linkage that operate in horizontal, vertical and inclined paths.
Industry:Mining
A continuous, seismic, median mountain range extending through the North and South Atlantic Oceans, the Indian Ocean, and the South Pacific Ocean. It is a broad, fractured swell with a central rift valley and usually extremely rugged topography; it is 1 to 3 km in elevation, about 1,500 km in width, and over 84,000 km in length. According to the 1985 hypothesis of sea-floor spreading, the mid-ocean ridge is the source of new crustal material.
Industry:Mining
A continuous, well-defined mass of material of sufficient ore content to make extraction economically feasible.
Industry:Mining
A continuously formed anode for aluminum production in which the mixture of petroleum coke and coal-tar pitch is continuously added to a steel casing and is baked as it passes through the heated casing, such that the baked anode emerging into the cell continuously replaces the anode being consumed.
Industry:Mining
A continuously formed electrode used in a metallurgical electrical furnace, in which a mixture of petroleum coke and coal-tar pitch is continuously added to a steel casing and is baked as it passes through the heated casing, such that the baked electrode emerging into the furnace continuously replaces the electrode being consumed; e.g., used in aluminum and ferroalloy production; may be oriented either vertically or horizontally.
Industry:Mining
A continuous-type filter made in the form of a cylindrical drum with filter cloth stretched over the convex surface of the drum. The drum rotates slowly about a horizontal axis, and the lower part is immersed in a tank containing the pulp to be filtered. Arrangement of pressure and suction pipes on the interior of the drum permits the application of suction to the filtering surface. As the filter passes through the tank, it picks up a layer of solid material and emerges carrying a layer of filter cake.
