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.


rocks on the one side and mill shell and toe of the grinding charge on the other side (FAG mills). The trajectories of grinding media and rocks promote size reduction by im-pacts. This grinding mechanism is required in SAG and FAG mill applications. 2. PERMEABILITY The main size reduction in this mechanism is carried out in the ball charge.
