Although PCDs are low-grade, they are important because they can be mined at a low cost on a large scale. Flotation is a common mineral processing method used to produce copper concentrates from copper sulfide ores. In this method, copper sulfide minerals are concentrated in the froth while associated gangue minerals are separated as tailings.
