摘　　要：以广西某地低品位高铁铝土矿为研究对象,开展磨矿产物工艺矿物学研究和浮选脱硅性质研究。考察磨矿细度,调整剂、分散剂和抑制剂用量及捕收剂用量对浮选指标的影响,探讨适合高铁铝土矿浮选脱硅的较佳工艺参数。原矿铝硅比为5.13的高铁铝土矿,经过一粗一精一扫的闭路试验后可获得浮选精矿铝硅比8.69,氧化铝回收率82.49%的浮选指标。Taking high - iron bauxite somewhere in Guangxi as research object, the studies of process mineralogy and desiliconization flotation properties were conducted. The influence of grinding fines, regulator dosage, dispersing agent dodge, depressants dosage and collecting agent dosage on flotation index were looked at and the suitable flotation parameters were investigated. The bench test result of flotation include that the concentrate A/S was 8.69, the recovery of alumina was 82.49%.
