某金尾矿综合回收长石试验研究

摘要

针对某金矿尾矿中含有金和长石等有用矿物，对其开展综合回收试验研究。结果表明，采用摇床对金矿尾矿进行分选，可获得金品位41.15 g/t、回收率46.84%的金精矿；摇床尾矿经脱泥-弱磁选-2段高梯度磁选联合工艺处理，可得到铁杂质（Fe2O3）含量0.23%，产率为57.39%的长石精矿，该产品达玻璃Ⅰ级和陶瓷Ⅱ级原料质量标准。%According to the valuable mineral of gold and feldspar powder in a gold tailing, the comprehensive utilization was introduced. The results show that a gold tailing was selected by shaker,the gold concentrate of grade 41.15g/t, yield 46.84%was obtained. Tailings in the shaker went through the desliming-weak magnetic-two stage strong magnetic combination process, and then the feldspar concentrate was obtained,whose contents of iron(Fe2O3)was 0.23% and the yield of was 57.39%. The ifnal product reached the ifrst grade quality level for the glass and the second grade quality level for the ceramics.
