某锡重选尾矿浮选回收锡试验研究
|
摘要
某锡重选尾矿仍含有品位约0.37%的锡,因矿石粒度较细且矿石性质复杂难以回收,采用硝酸铅和苯甲羟肟酸的有效组合药剂,实现锡的高效经济回收。通过预先脱泥后一粗一精的简单浮选工艺,取得锡精矿中锡品位和回收率分别为2.82%、53.66%的良好指标。
A gravity separation tailings of cassiterite still contains tin with grade of about 0.37%,and it was difficult to recover tin due to its fine-grained ore size and complex ore property.Using the effective combination of lead nitrate and benzyl hydroxamic acid,high efficiency and economic recovery of tin was achieved.A good result with tin grade of 2.82% and recovery of53.66%in tin concentrate was achieved by using simple flotation processing circuit of one-stage roughing and one-stage cleaning with pre-desliming.
