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 computer that operates with numbers represented by directly measurable quantities (such as length, voltage, or resistance) in a one-to-one correspondence; a measuring device that operates on continuous variables represented by physical or mathematical analogies between the computer variables and the variables of a given problem to be solved.
Industry:Mining
A concave projection at the upper edge of a ladle to guide the metal in pouring.
Industry:Mining
A concealed arch carrying the backing or inner part of a wall where the exterior facing material is carried by a lintel.
Industry:Mining
A concealed brick header in the interior of a wall, not showing on the faces.
Industry:Mining
A concentrated and viscous solution of sodium silicate or potassium silicate in water. Used as an adhesive, a binder, a protective coating, in waterproofing cement, and in bleaching. Colorless; amorphous; Na<sub>2</sub>O.XSiO<sub>2</sub>, in which X = 3 to 5; deliquescent.

Industry:Mining
A concentrating device that exploits differential densities of coal and its associated impurities by a combination of sluicing and centrifugal action. The material gravitates down through a stationary spiral trough with six turns (five for ore treatment) of mean radius 8 in (20.32 cm) with a fall per turn of 11 in (27.94 cm). Heavy particles stay on the inside, the lightest ones climb to the outside, and the resulting bands are separated at convenient points.
Industry:Mining
A concentration of naturally occurring solid, liquid, or gaseous material in or on the Earth's crust in such form and amount that economic extraction of a commodity from the concentration is currently or potentially feasible.
