Company Profile:
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 ...
As defined by its opposite, land is not vacant when occupied as a mining claim without discovery by one who is diligently prospecting it for minerals that it may contain.
Industry:Mining
As deliberately used in roll crushing of ore, feed at a rate greater than can be discharged at the set of the machine, so that the rolls are sprung apart, the angle of nip is increased, and the product contains oversize.
Industry:Mining
As opposed to hindered settling in classification, free fall of particles through fluid media.
Industry:Mining
As sometimes practiced, this method is a combination of bulk oil flotation and froth flotation. By adding large quantities of kerosine to a pulp plus a small amount of frother 1702 and agitating vigorously, surfaces of the amenable mineral (coal) are attracted to both the oil and air bubbles, forming heavy flocs. This type of concentrate is more readily dewatered than ordinary froth and therein lies its advantage, plus the fact that coarser particles (6 to 10 mesh) can be handled than in ordinary froth flotation.

As used by foundation engineers, the act or process of sinking holes into the overburden (sometimes to considerable depth into bedrock) with rotary or drive sampling equipment for the purpose of recovering samples from which information on the physical characteristics of the materials penetrated can be obtained; also applied to the sample or samples so obtained.
