| 摘 要： | 对某含锡0.86%、含硫2.14%的锡石多金属硫化矿进行了选矿工艺研究。采用混合浮选脱除其中硫化矿物, 然后混合浮选尾矿采用离心机预先抛尾-分级摇床-浮选工艺回收其中的锡, 试验室闭路试验获得锡品位55.63%、回收率61.83%的摇床锡精矿和锡品位29.31%、回收率11.33%的浮选锡精矿, 锡总回收率为73.16%。试验指标较为理想。

| Abstract: | A study on the mineral processing of some cassiterite-polymetallic sulfide containing 0.86% Sn and 2.14% S was presented. In the test, a bulk flotation process was firstly adopted to remove sulfide. Then, the obtained tailings was subjected to a pretreatment with centrifuge for discarding tailings, followed by a shaking table for classification and flotation process to recover tin. A laboratory closed-circuit test resulted in a tin concentrate approaching 55.63% Sn grade at 61.83% recovery from shaking table and a tin concentrate grading 29.31% Sn at 11.33% recovery from flotation, with a total recovery of tin reaching 73.16%, showing a relatively good process result. |
