Grate Discharge Ball Mills: In this type of mill, the ground materials are discharged through the grate plate, which prevents the grinding media from exiting the mill. ... They are widely employed in both wet and dry grinding processes for the comminution of materials such as gold, copper, iron, and lead-zinc ores.
Mexico, Kazakhstan, Zambia, and Congo. Chile accounted for almost a third of global copper produc-tion in 2018. The largest volume of processing is currently asso-ciated with porphyry copper, copper sandstones and slates, and copper-pyrite deposits in Russia. The ores of sulfide copper-nickel, copper-pyrite deposits, and
