某含铜转炉渣回收铜浮选试验研究
|
摘要
某铜转炉渣中铜品位为2.78%,铜元素主要以冰铜微珠的形式赋存于炉渣中,冰铜分布较为分散,嵌布粒度大小悬殊,不易单体解离.为了高效回收二次资源,针对该铜转炉渣的性质特点,进行了浮选试验研究.结果表明:在磨矿细度≤0.074 mm占80%,酯-200作为捕收剂,粗选时间为9 min的条件下,采用"一粗-一精-一扫"浮选工艺,实验室闭路实验可获得铜品位和回收率分别为31.64%和94.16%的铜精矿.
The grade of copper in a copper converter slag is 2.78 %. Copper is mainly existd in the slag in the form of iced copper microbeads. The distribution of matte copper is more dispersed, and the size of the embedded copper is disproportionate, which makes it difficult for the monomer to dissociate. To recover secondary resources efficiently, a flotation test was conducted in view of the characteristics of the copper converter slag.The results showed thatcopper concentrate, with the grade and recovery being 31.64 % and 94.16 % respectively, were obtained when the grinding fineness of less than 0.074 mm accounted for 80 %,ester-200 as collector, roughing time under the condition of 9 min.
