中文摘要: 本文以大红柳滩某锂铍多金属矿为研究对象，研究了N甲基9十七烯酰胺基乙磺酸钠和N-甲基脂肪酰胺基乙酸盐作清洗剂时矿物表面清洗浮选对锂铍矿物可浮性及锂铍分离效果的影响，并对矿物表面清洗浮选的试验条件进行了优化。闭路试验的结果表明，在磨矿细度-0.074 mm 72%的条件下，清洗浮选可以获得锂精矿Li2O品位为6.01%，Li2O回收率为87.60%；铍精矿BeO品位6.57%，BeO回收率62.90%的良好指标。其中，锂精矿中BeO品位为0.049%，BeO回收率为31.20%，较好地实现了锂铍分离。
Abstract:In this paper, a lithium-beryllium polymetallic ore in Dahongliutan region was taken as the research object. The effects of mineral surface cleaning flotation on the floatability of lithium-beryllium minerals and the separation effect of lithium-beryllium minerals were studied when N-methyl-9-heptadecene amide sodium sulfonate and N-methyl fatty amide acetate were used as cleaning agents. The experimental conditions of mineral surface cleaning flotation were optimized in this study. The results of closed-circuit test show that under the grinding fineness of -0.074 mm 72%, the lithium concentrate with Li2O grade of 6.01% and Li2O recovery of 87.60%, and the beryllium concentrate with BeO grade of 6.57% and BeO recovery of 62.90% can be obtained. At the same time, the grade of BeO in the lithium concentrate is 0.049% while the recovery of BeO is 31.20%, which means lithium-beryllium separation can be achieved by the cleaning flotation process.
