摘　　要：针对新疆某辉钼矿嵌布粒度较细、可浮性较差的特点,应用价格便宜、选择性好且捕收能力较强的新型捕收剂GR-713,采用"一次粗选,两次扫选,粗精矿再磨七次精选"的浮选流程,获得了较好的选矿指标:钼精矿品位45.85%,回收率86.41%。For a molybdenite ore in Xinjiang with characteristics of fine-size disseminated and poor flotability,GR-713,a new,cheap collector with good selectivity and collecting ability was applied.The concentrate of 45.85%Mo was obtained with a recovery of 86.41% by a flotation process of one stage roughing,two stages scavenging and seven stages cleaning after rough concentrate regrinded.The processing data is good.
