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 ...
Similar to a front end loader; a low-profile loader articulating in the center with a large bucket in front (usually five tons or more) that transports ore in an underground mine. The operator sits at sideway controls facing the loader and drives it in either direction as required. Usually used for loading ore cars, shuttle cars, or hauling directly to an ore pocket.
Industry:Mining
Similar to a Wilfley table but of diamond shape (rhomboid), thus eliminating the waste corners.
Industry:Mining
Similar to octant search, but using four sectors instead of eight sectors. Applies to any interpolation method where a limited number of sample data points are used to estimate intermediate values.
Industry:Mining
Similar to the Blake crusher, except the movable jaw is hinged at the bottom. Therefore the discharge opening is fixed, giving a more uniform product than the Blake with its discharge opening varying every stroke. This type of jaw crusher gives the greatest movement on the largest lump.
Industry:Mining
Similar to the continuous bucket elevator, it is often used in sand and gravel plants where the dredge line discharges to a sump. The dewatering elevator digs the material from the sump, allowing the water to drain out through perforations in the backs of the buckets while being elevated, and discharges to the plant for further processing.
Industry:Mining
Similar to the hopper dredge except that the discharge, instead of going into hoppers or directly back into the sea, is carried in a discharge pipe hung from a boom, a distance of from 200 to 500 ft (60 to 150 m) directly to port or starboard of the vessel, and there discharged into the atmosphere, dropping vertically from a height of about 50 ft (15 m) onto the surface of the sea. The drag heads of the dredge provide a channel, and the excavated soil is spread over a wide shoal area on either side, without the necessity of hauling it to the sea.
Industry:Mining
Simple and speedy qualitative tests used to identify minerals species when prospecting, valuing a deposit, or testing mill products.
Industry:Mining
Simulation of in-situ leaching through the use of a long narrow column in which ore sample and solution are in contact for measuring the effects of typical variables encountered in actual in-situ leach mining.
