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 steelmaking process in which oxygen is forced at supersonic speed through a retractable water-cooled lance, accelerating the burning off of unwanted elements in a charge of molten iron and scrap.
Industry:Mining
A steelmaking process in which the air blown through the bottom tuyeres is enriched with oxygen. If oxygen alone is used, tuyere wear is excessive. Oxygen plus steam or oxygen plus carbon dioxide can be used.

Industry:Mining
A steelmaking process using the principle of rotation as in the Kaldo process. It has two lances; one above the bath surface uses low-pressure oxygen to burn carbon monoxide from the bath, while the other blows oxygen onto the bath at high pressure to obtain similar fast oxidation as in the L.D. steel process.
Industry:Mining
A steelmaking process, either Bessemer, open-hearth, or electric, in which the furnace is lined with a basic refractory, a slag rich in lime being formed and phosphorus removed.
Industry:Mining
A steelmaking process--Bessemer, open-hearth, or electric--in which the furnace is lined with a siliceous refractory, and for which pig iron low in phosphorus is required, as this element is not removed.
Industry:Mining
A steel-wire rope, generally of the same weight per foot as the main winding rope, that is attached to the bottom of the cages, and extends down to form a loop in the shaft bottom 226 or sump. Its function is to balance out the difference in weight of the upgoing or downgoing main ropes during the wind.
Industry:Mining
A steep ascendent of salinity. This has an effect on refraction of sound waves, since sound velocity increases with increasing salinity.
Industry:Mining
A steep ring-shaped fault, complete or incomplete. It is associated with cauldron subsidence.
Industry:Mining
A steep to vertical fault associated with a low-angle overthrust fault and occurring in the hanging wall. It strikes perpendicular to the strike of the overthrust; displacement may be horizontal, and there may be a scissor effect. It is considered by some to be a type of strike-slip fault.
