mining should be encouraged, through fiscal in-centives and taxation to progressively move to-wards full-scale beneficiation and value-addition as close to the extraction point as possible. If a mining company chooses to concentrate on its primary and core business of mining and min-imal beneficiation, then it should be encouraged

The iron ore beneficiation production line uses a variety of screening equipment, such as vibrating screens, trommel screens, etc. 3.Grinding. The pretreated ore is finely ground to achieve the required particle size. Iron ore beneficiation production lines mostly use ball mills for grinding. 4.Magnetic separation

African countries, Zimbabwe included, continue to be haunted by the "resource curse" over failure to use their mineral wealth to transform their economies. They are among resource-rich countries that have seemingly failed to leverage on mining through beneficiation and value addition. Value adding mineral resources involves processing them into semi-processed …
