    Beneficiation And Mineral Processing Of Sand And Silica Sand

    Iron ores are rocks and minerals from which metallic iron can be economically extracted during the mining process. Waste elements other than iron (Fe) in iron ore dilute the overall grade of the ore and incur a smelter penalty. Penalty elements change the physical properties of iron and can impede the proper operation of the smelting facility.Junior miner Atlas Iron's approach had been to quickly get its low grade (57.5 Fe) direct shipping (hematite) ore to China to generate cash flow to develop other mines. It was a very simple operation after minimal processing the ore was trucked the short distance to Fortescue Metals Group's rail facility, loaded and taken to Port Hedland for.
