摘要
为回收某尾矿中的硫矿物,针对尾矿中磁黄铁矿含量高的特点,分别进行了先浮后磁流程和先磁后浮流程试验。2个方案均采用一粗一扫三精流程和硫酸活化,通过先浮后磁闭路试验,得到了综合硫精矿硫品位为35.08%,硫回收率为93.65%的试验结果;通过先磁后浮闭路试验,得到了综合硫精矿硫品位为33.92%,硫回收率为92.15%的试验结果。通过试验证明,先浮后磁方案较佳。
To recycle sulfur mineral from a certain separated zinc tailings, in view of high content of pyrrhotite in tailings, the experiments separately ~nvolving magnetic separation after flotation as well as flotation after magnetic separation were conducted. Both two schemes consisted of a roughing, a scavenging, three concentration and sulfuric acid activation. Through the closed-circuit experiment involving magnetic separation after flotation, sulphur concentrate with sulfur grade of 35.08% and sulfur recovery rate of 93.65% was obtained. Through the closed-circuit experiment involving flotation after magnetic separation, sulphur concentrate with sulfur grade of 33.92% and sulfur recovery rate of 92.15% was obtained. The contrast results showed that the scheme involving magnetic separation after flotation was superior.
