Aluminum Manufacturing Multilateral Investment Guarantee Agency

The production of aluminum begins with the mining and beneficiation of bauxite. At the mine (most of which are of the surface type) bauxite ore is removed to a crusher following which the crushed ore is screened and stockpiled ready for delivery to an alumina plant. In some cases, ore is upgraded by beneficiation (washing
