| 摘 要： | 国外某锡矿矿山存在着细泥中锡金属流失严重的问题,细泥中的锡石嵌布粒度细小,含有大量可浮性好的硫化矿物及碳酸盐矿物,拟采用浮选方案处理该含硫锡石细泥。在条件试验和对比试验的基础上,确定了先浮选脱除硫化矿,脱硫尾矿采用水杨羟肟酸和P86组合捕收浮选锡石的选别工艺。全流程闭路试验获得了Sn品位19.85%,回收率88.00%的锡精矿。

Test study on lfotation of an overseas sulifde-bearing cassiterite slime |

| Abstract: | Large loss of tin in ifne slime was a serious problem in an overseas mine. The slime contained ifnely-disseminated cassiterite and lots of sulphide and carbonate minerals with good lfotability, so the lfotation scheme was determined to process the sulifde-bearing cassiterite slime. After conditional test and contrast test, the beneifciation process was determined, which was involved lfotation to remove sulphide and then lfotation of desulfurized tailings with combined collectors of salicylhydroxamic acid and P86 to recover tin. After complete closed-circuit lfow test, the tin concentrate with Sn grade of 19.85% and recovery ratio of 88.00% was obtained. |
