摘　　要：针对齐大山难选铁矿的性质,设计和合成了KS-Ⅱ捕收剂。实践表明,该药剂具有用量少、选择性高、捕收能力强、易分离和降解等特点。与原捕收剂相比,精矿品位提高0.30%、尾矿品位降低0.70%、药剂耗量减少30%。Based on the property of Qidashan difficult--to--separation oxidation iron ores a KS-Ⅱ flotation reagent is designed and synthesized. The industry applications in Qidashan Flotation Ore Factory show that the collector possesses fewer unit consumption, high selectivity, excellent collection ability, easy to operate and quick nature metabolism compared with now collectors. Compared with RA--515 flotation reagent, the collector can improve 0.30% Fe concentrate grading, decrease 0.70% Fe concentrate in gangue, reduce 30% unit consumption of collector.
