Crushing and Grinding You will note that the Oracle Ridge project has utilized a two-stage crushing circuit with a double acting jaw crusher and cone crusher. In order to utilize this system, the jaw crusher is oversized to produce all -5 material for the cone mill with a screen in closed circuit. Normally a three-stage crushing circuit would have been more conventional, but with the type of

The response parameters in flotation are dependent, among other factors, upon the pulp chemical condition right from the stage of grinding through flotation. The present work deals with the results of investigations carried out at different stages in the grinding and flotation circuits of a plant, treating a low grade copper ore.

The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit. The designed ball milling circuit product is 80% passing 150 µm.

The grinding tests were carried out in a vertical mill (JM-2, Changsha, China) at a constant rotational speed of 450 rpm. To better verify the effects of the grinding media on grinding products and chalcopyrite flotation behavior, the mill barrel was made of corundum with a volume of 200 mL, and the top of the stirring rod was covered with a nylon material.
