<p>Agglomeration of ferrous minerals is controlled to give a final desired permeability using the min. amt of water by making water additions into two mixers. The additions of water are divided between the two mixers. e.g. a greater amt is added to the first mixer, which amt is reduced as the amt added to the second mixer is increased, until a required permeability is obtd.</p> |
