摘要
江西某选铅尾矿中含有锌,该锌属于难选锌矿石,嵌布粒度较细,通过系统的选矿试验,结果表明:采用一次粗选两次扫选、粗精矿再磨、再进行三次精选的工艺流程可以获得品位为46.82%,回收率84.76%的合格锌精矿,选别指标很好.
The zinc ores contained in the lead dressing tailings are refractory and fine-grained. The mineral processing testing results show that the combined flowsheet of one rough selection and twice sweeping selection, crude concentrate regrinding, fine process, obtains zinc concentrate with grade of 46.82 %. The recovery rate is 84.76 %.
