How to use comminution processes for reducing the ore

These operations are necessary before applying any separation method to concentrate the ore because the liberation of valuable minerals from the host rock is needed In most cases both crushing and grinding are employed but if the run of mine is already in the form of small pieces the ore passes directly to the grinding circuit

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

Ore Dilution Recovery in Mining

Recovery and dilution usually are interrelated with some methods of stoping a high recovery involves contamination of the ore from the walls or capping and often clean ore can be obtained only by leaving some ore in the mine In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall The amount of ore thus left varies considerably
