摘　　要：针对鞍千矿业原矿的特点和性质,采用一种新型KS-Ⅵ捕收剂和改性淀粉抑制剂对鞍千矿业铁矿石进行反浮选试验,与原氢氧化钠-淀粉-氧化钙-RA-715四种组合药剂相比,在精矿品位相近的情况下,尾矿降低3.50%以上、浮选作业回收率提高3.27%左右。新药剂不仅能提高选矿指标,而且可简化药剂制度,为鞍千难选铁矿石提铁降硅提出了一条新的途径。Based on the property of Anqian iron ores, new KS-- Ⅵ collector and starch inhibitor improved are applied in reverse flotation on Anqian Flotation Ore Factory. KS--Ⅵ flotation reagents, compared with the system of the traditional NaOHWStarch＋CaO＋RA--715, can decrease 3.50% Fe concentrate in gangue, improve the recovery of 3.27% under the same Fe concentrate grading. New agents are not only superior in beneficiation index, but also can simplify the agents system, to list the new method of ＂improve Fe and decrease Si＂ on Anqian Difficult--to--separation iron ores.
