The experiment study on a low-grade refractory iron ore in Hebei province

The composition of A Iron Ore in Hebei Province is complex and it,s grade is low.It is difficult to separating Fe and Ti because magnetite which is main useful mineral is compact with ilmenite and hematite containing titanic.it is disadvantageous for recovering Fe because there many kinds mineral containing and gangue mineral.The index of is grade of Fe concentrate being 65.75,the recovery of Fe concentrate being 52.01,the content of magnetism Fe in tailing being 0.92%,the trcovery of magnetism Fe in concentrate being 90.31%are got on the condition of flowsheet of staggered grinding staggered magnetic separation,the gringing fineness of the first stage being 46.91%,the gringing fineness of the second stage being 96.17%.
