【摘要】 以白云鄂博选铁尾矿为研究对象,进行了优先浮选回收稀土的工艺研究,根据试样的矿物学性质,采用羟肟酸类捕收剂LF-P8,水玻璃为抑制剂,松醇油为起泡剂,在矿浆pH值9.0、温度60℃下,经过"一粗三精,中矿集中返回"的浮选闭路工艺可以得到品位(REO)50.52%、回收率(REO)81.30%的稀土精矿,成功实现选铁尾矿中稀土资源的高效回收利用。更多还原

【Abstract】 Taking Bayan Obo iron tailings as the research object,the preferential flotation recovery of rare earth technology was studied.According to the mineralogical properties of the sample,the hydroxyl oxime acids collector LF-P8 was used,and water glass was used as the inhibitor,the terpenic oil is a foaming agent.At a pH of 9.0 and a temperature of 60℃,The flotation closed-circuit process of"one roughing,three refining,medium ore returns after merger"was used to treat samples,and the rare earth concentrate with a grade(REO)of 50.52% and a recovery rate(REO)of 81.30% can be obtained.It has successfully realized the efficient recovery and utilization of the rare earth resources in the iron tailings.更多还原
