A minimum of -35 mesh BSS has been found necessary to give 95% recovery of the contained manganese. Grinding of reduced ore is easier, since the reduced ore is much softer, but grinding also reoxidizes some of the manganese, which affects the leach recovery to some extent. Therefore, grinding to -35 mesh preceeds reduction.
