A reaming shell in which no reaming diamonds or other cutting media are inset on the outside surface.
Industry:Mining
A reaming shell, a portion of the outside surface of which has embedded diamonds, diamond-inset inserts, or other cutting media, having a set diameter slightly greater than the standard set size of the bit to which the shell is coupled.
Industry:Mining
A reaming shell, the reaming diamonds of which are inset in shaped, hard, metal plates brazed into grooves cut into the outside surface of the shell.
Industry:Mining
A recently developed process for use in fine-particle flotation. The underlying principle is the use of a finely ground (minus 325-mesh) auxiliary mineral as a carrier for the fine particles to be floated. The fine particles form a slime coating on the carrier mineral; the carrier mineral is then floated, and the fines are piggybacked into the froth.
Industry:Mining
A reciprocating beam or beams with hinged flights arranged to advance bulk material along a conveyor trough.
Industry:Mining
A reciprocating drill mounted on a bar by means of which holes are drilled close together in line by shifting the drill from point to point along the bar. Thereafter, the webs between the holes are removed with a reciprocating chisel-pointed broaching tool that is substituted for the drill. This method of channeling is generally employed in the harder rocks, such as granites.
Industry:Mining
A reciprocating engine operated by compressed air which is used to impart the reciprocating motion to a shaker conveyor panline.
Industry:Mining
A reciprocating single- or double-action piston pump having one water cylinder.
Industry:Mining
A reconnaissance method in which a plane follows an outcrop along steep canyon walls, keeping where possible within 50 ft (15 m) of the face of the cliff. This type of prospecting has been successful in discovering new deposits in the Colorado Plateau region.
