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 flotation, a system in which the manipulated variable alternates between two predetermined values.
Industry:Mining
In flotation, floating control in which the manipulated variable changes at a fixed rate, increasing or decreasing depending on the sign of the actuating signal.
Industry:Mining
In flotation, any of a group of nonionizing hydrocarbon oils that act as collector agents by smearing action, giving aerophilic quality to the surface they selectively coat.
Industry:Mining
In flotation, that portion of an automatic feedback control system that compares functions of a controlled variable and a command and adjusts a manipulated variable as a function of the difference. It includes the reference input elements, summing point, forward and final controlling elements, and feedback elements.
Industry:Mining
In flotation, one of the bubbles that rise from the pulp loaded with particles of desired mineral.
Industry:Mining
In flotation, that portion of the feedback elements that converts the signal from the primary detecting element to a form compatible with the reference input.
Industry:Mining
In flotation, the component of control action in which the final control element is moved at a speed proportional to the extent of proportional position action. This term applies only to a multiple action including proportional position action.
Industry:Mining
In flotation, the interval of time between initiation of an input and the start of the resulting response. It may be qualified as effective if extended to the start of the buildup time, theoretical if the dead band is negligible, and apparent if it includes the time spent with an appreciable dead band.
Industry:Mining
In flotation, the range through which an input can be varied without initiating response.
Industry:Mining
In fluidization roasting (fluosolids process), the conversion of iron sulfide to magnetite.
