Mine-To-Mill Optimisation: Effect Of Feed Size On Mill ...

If drill and blast costs need to be increased to improve the quality of fragmentation, these costs are far outweighed by the reduction in mill operating costs – typically 7 to 10 times any increase in mine costs. At the same time, the concentrator must be prepared to take advantage of the much improved, higher quality feed material.

Mine Operations - Venice Mine Complex

The ball mill discharges the resultant slurry via a trammel screen to the gravity concentrator. Any material not collected in the concentrator is pumped to a cyclone at the head of the CIL plant and treated with cyanide. Gravity Circuit Ore particles are subjected to a force of 60 gravities in a fluidization process in a Knelson Concentrator.

The operating principle of the ball mill

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.

Knelson concentrator - Wikipedia
