Grinding is performed using a Rod Mill operating in closed circuit with a Vibrating Screen. This procedure provides a minus 20 mesh product for subsequent table treatment and minimizes overgrinding of the cassiterite. Depending on the characteristics of the ore, the possibility of using a Peripheral Discharge Rod Mill should be studied.
