Primary Milling Circuit – In high grade mills this can be a good target, however it is much less likely to be economic in the large lower grade mills (0.3 g/t). A gravity installation in the primary milling circuit will reduce the amount of gold in any downstream recovery circuit; therefore, this must be taken into account when performing downstream economic calculations.
