The Jameson Cell is particularly suited for Removal of naturally hydrophobic gangue (carbon and talc) at the head of the flotation circuit where Jameson Cells act as roughers, or rougher cleaners, minimising entrainment of the valuable minerals to the 'throw away' concentrate. Performance that mechanical cells simply cannot match.
