Manganese Ore Processing
· Screen No. 3. As the market requires that not more than 10% of the shipping ore is minus 20mesh, the selective jig concentrates are passed over a singledeck, 2'x 4′ Dillon Vibrating Screen, with 20mesh screen cloth. The plus 20mesh screen oversize becomes shipping ore and the minus 20mesh manganese is stock piled for future marketing.
