Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

The most well known carbon-in-pulp plant remains the prototype Homestake plant in Lead, South Dakota. Operating since 1973, this facility treats 2130 tonnes of ore per day averaging 2.7 g gold per tonne. Homestake has also operated small silver carbon-in-pulp plants at Creede and Cripple Creek, Colorado since 1979.
Mining at Crawford nickel-sulphide project. ... (ROM) ore will undergo primary and secondary crushing in a semi-autogenous grinding (SAG) mill and a ball mill grinding circuit, followed by desliming through hydrocycloning. ... The process plant for the project will be developed in three phases. Phase one development will include a …
be AG primary milling and secondary ball milling. Flotation is again done in stages between the milling circuits. A recent exception to this has been the Kroondal operation, where the primary comminution stage uses a rod mill. Here and at one other conventional plant, dense media separation is used to sepa-rate the barren norite stringers from the
