Draft Mineral And Energy Policy African National Congress

To consider the imposition of a small levy on all minerals extracted, based on the tonnage removed (depleted). Such levies should be low so as not to inordinantly raise the investment threshold and should be mineral specific.

D. Beneficiation

Traditional beneficiation facilities produce a throughput value for raw ore which is, in some cases, clearly below 1 t/MS. As a result, smallscale mining processing operations in developing countries are laborintensive. The problem is intensified by the fact that, as a rule, the beneficiation is performed as a noncontinuous
