BLASTING TECHNICAL INFORMATION

Blast nozzle spray patterns are affected by orifice size, air pressure, and distance from the workpiece. The total diameter of the blast pattern increases as the distance from the workpiece is increased. The hot spot (where work speed is maximized) can be obtained at larger distances from the workpiece with pressure air blast systems.

Abstract

Crushed ore is then ground in a ball mill and sent through cyclones. The oversize is returned to the ball mill, while the undersize is sent to a grinding thickener. The overflow from the thickener is also returned to the ball mill, while the underflow goes through a series of agitated leach tanks, where cyanide is added to the slurry.
