某低品位铝土矿的重选可行性试验研究

摘要

The low-grade bauxite ore from Henan province whose mass ratio of aluminium oxide to silicon dioxide was about three was taken as study object. After float-sink experiment, a shaking table and a teetered bed separator were used to conduct expriments so as to investigate if gravity separation of the bauxite ore was feasible. Finally, the concentrate whose mass ratio of aluminium oxide to silicon dioxide was about six was obtained. The study results showed that the gravity separation was of significance for separation of the low-grade bauxite ore.%以河南某铝硅比为3左右的低品位铝土矿为研究对象，在浮沉试验的基础上，通过摇床分选、干扰分选床（TBS）分选，对该低品位铝土矿的重选可行性进行试验研究，获得了铝硅比为6左右的精矿。研究结果表明，重选对该低品位铝土矿的分选具有重要的意义。
