摘要:
THIS invention relates to an integrated process for recovering the valuable iron fraction from low grade iron ore, including the steps of: comminution 14 and classification 36/39 to obtain a classified fraction suitable for coarse flotation and classified fraction suitable for fine beneficiation; subjecting the fraction suitable for coarse flotation to coarse flotation 40 to obtain an intermediate iron concentrate 42 and a coarse sand residue 44; grinding the intermediate concentrate to a size suitable for fine beneficiation; and subjecting the fractions suitable for fine beneficiation to fine beneficiation 46 and obtaining a final iron concentrate 48 and a fine tailings 50.
