Each of the milling lines consists of a primary autogenous (AG) mill and a secondary ball mill. Following the AG mill the first stage of magnetite separation produces low grade concentrate and rejects non-magnetic tails at coarse size. Another two stages of magnetic separation occurs after the ball mill to produce final high grade concentrate.
