Dry beneficiation of lowgrade goethiterich iron ore fines by air ...

In mining and minerals industries, whenever water supplies are restricted and also where wet processing leads to problems in handling and dewatering of the products and tailings, dry beneficiation is preferred. Moreover, the decrease in available highgrade iron ores has generated a need to develop alternative beneficiation processes for processing lowgrade iron ores.
