【摘要】 分析了鲕状赤铁矿难选的原因,针对鲕状赤铁矿粒度特征,分析了各种选矿方法脱磷和提铁的效果。结合已有的研究成果,对重选、强磁选、浮选等方法的选矿效果作了预期。针对该矿磨矿容易泥化的特征,指出了阶段磨矿和阴离子反浮选是最经济有效的提铁降磷的方法,具有节能和高效的特点。对于认识和开发利用鲕状赤铁矿具有参考价值,为以后的开发奠定基础。更多还原

【Abstract】 AnalyzeD the causes of difficult separating Oolitic hematite,base on the size analysis of this refractory iron ore,discussed the effects of common methods for dephosphorization and iron enrichment.According to results of other researchers, expected the effects of the gravity,high intensity magnetic and flotation separation methods.Considering of the sliming in grinding,point out that the flow sheet of stage grinding and anionic reverse floatation is the most effective and economic method.This will provide a reference for understanding and developing Oolitic hematite ore,and lay a foundation for exploitation.更多还原
