The underflow is sent to a secondary ball mill and trommel screen, for additional grinding and classification. Using froth flotation, the copper minerals separate from the gangue and rise to the froth layer of the flotation cell. In turn, the copperrich bubbles are removed or transferred to the next stage of flotation for further processing.
