以宜昌某高磷鲕状赤铁矿为研究对象进行反浮选提铁降磷试验研究,通过化学多元素分析、物相分析、工艺矿物学分析考察原矿的性质,研究了浮选捕收剂、抑制剂、矿浆温度、矿浆浓度等因素对浮选指标的影响。试验结果表明:采用复合脂肪酸捕收剂(MG∶MY=2∶1),用量为300 g/t时,经过一段粗选两段精选,获得了精矿铁品位57.43%,回收率71.80%,含磷量0.18%的浮选指标,为该类型矿石的开发利用提供了重要的技术依据。
Taking a high-phosphorus oolitic hematite from Yichang as the research object, the iron recovery by reverse flotation was studied. The chemical properties of ore were investigated by chemical multi-elemental analysis, phase analysis and technological mineralogy. The effects of flotation collector , Inhibitors, pulp temperature, pulp concentration and other factors on the flotation index. The results showed that the concentrate grade was 57.43% and the recovery rate was 71.80% when the compound fatty acid collector (MG: MY = 2:1) was used at a dosage of 300 g / , Flotation index of 0.18% phosphorus content provides an important technical basis for the development and utilization of this type of ore.
