浮选药剂联合使用及其在煤泥浮选中的应用研究

由于药剂协同作用的存在,在将高活性的芳烃MA捕收剂和高选择性的煤油捕收剂混合使用的时候,完善指标最高可超过53,在MA含量为0.4的时候精煤产率和灰分可达为81.8%和11.85%,相对于单一使用MA或煤油在保持高产率的同时,起到了降低灰分,提高完善指标的作用。 The high active collector MA and high selectivity collector kerosene were mixed used in coal slime flotation by reason of the coordinated action of the different reagent.When they were mixed used,the flotation perfect guide line can be more than 53,and the produce and ash concentrate of cleaned coal can reach to 81.8% and 11.85% by the time of MA concentrate is 0.4.Mixed reagent used in coal slime flotation to reduce the ash concentrate and heighten the perfect guide line related to just use MA or kerosene collector
