摘　　要：云南某锡矿主要采用摇床重选回收锡矿物。为了提高锡金属的回收率,针对摇床重选尾矿进行了不同的选矿工艺探索试验。生产实践表明,采用:“预先脱粗-脱泥-摇床重选”工艺,锡金属得到有效回收,每年可以产出品位为3.20%的粗锡精矿1450 t,年创效为159.51万元。Table concentrator gravity separation is mainly adopted for recovery of tin metal from one Yunnan tin mine.The different probe trial of mineral processing technology for table concentrator gravity separation tailings is carried out in order to improve the recovery rate of tin metal.The production practice show,adoption of pre-rough removal-desliming-table concentrator gravity separation process,therefore tin metal can be recycled effectively,the annual yield is 1450 t crude tin concentrate with 3.20%grade,which can create benefits of 1.5951 million yuan.
