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 ...
In mineral processing, development of the desired condition of the particles by defined states, such as comminution to successively fine sizes (possibly coupled with staged concentration or gangue elimination) between such stages of communition.
Industry:Mining
In mineral processing, final stage in flotation of mineralized froth before discard of tailing. The cells are so worked as to remove for retreatment as much low-grade rising mineral as possible under the given working conditions.
Industry:Mining
In mineral processing, flotation collector agents, marketed as Aerofloats by the American Cyanamid Co.
Industry:Mining
In mineral processing, the concentrates passing down through the ore jig into the hutch.
Industry:Mining
In mineral processing, the delay or retardation in the response of the controlled variable at a point of measurement to a change in value of the manipulated variable.
Industry:Mining
In mineral processing, the general physical and chemical conditions of a pulp, in which the pH, added chemicals, solid-liquid ratio, temperature, particle size range, and ionization of a flotation pulp are held within controlled limits while a considerable number of associated factors of less direct importance to the surface chemistry of the process are, at best, only indirectly monitored.
Industry:Mining
In mineral processing, the variable whose control is the end purpose of the automatic control system.
Industry:Mining
In mineralogy, a mineral showing differences in color, other physical properties, or minor variations in composition from the material considered typical of the species. An example is emerald, the green-colored gem beryl.
Industry:Mining
In mineralogy, both isomorphous and dimorphous; said of certain groups of minerals.
Industry:Mining
In mineralogy, forming an incrustation or deposit of grains or powder that resembles lichens or dried leaves; not uncommonly due to loss of water of crystallization.
