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 ...
Flattened bars of iron with holes punched through them for bolts. The holes are made somewhat larger than the bolt to permit rail expansion and contraction.
Industry:Mining
Flawless quartz, which can be used in the manufacture of oscillator plates.
Industry:Mining
Flotation cells in which the bulk of the gangue is removed from the ore or coal.
Industry:Mining
Flotation process practiced on a shaking table. Ore or coal is ground, deslimed, conditioned, and fed to table as thick slurry. Flotable particles become glomerules, held together by minute air bubbles and edge adhesion. These roll across and are discharged nearly opposite the feed end. The process is helped by jets of low-pressure air from piping set across table. Tailings work along deck to discharge end.
Industry:Mining
Flotation reagents made by DuPont are D.P. 243, a 50% aqueous paste of lorolamine (lorol being a mixture of primary straight-chain alcohols) and D.P.Q., lauryl trimethyl ammonium bromide. Others include D.P.Q.B., D.P.C., D.P.N., and D.P.L.A.
Industry:Mining
Flow in the same direction of two or more streams within a stream system.
Industry:Mining
Flow in which the relationship of the shear stress to the rate of shear strain is nonlinear; i.e., flow of a subsurface in which viscosity is not constant.
Industry:Mining
Flow layer resulting from incipient fusion during polishing of mineral surface, and therefore not characteristic of true crystal structure.
