摘要
浙江某低品位矾矿矿石性质复杂,嵌布粒度细,采用一次粗选三次精选两次扫选中矿依次返回的碱法浮选流程进行浮选试验,再将浮选得到的明矾石精矿经高梯度强磁选除铁,最终获得的明矾石精矿含Fe2O31.71%,SO3品位28.78%,SO3回收率82.23%。产品质量超过了明矾石特级品要求。
Flotation tests were carried out for a low grade alunite ore from Zhejiang Province by adopting alkali flotation flowsheet of one roughing-two scavenging-three cleaning and the middling returning in turn.Iron in alunite flotation concentrate was removed by using high intensity magnetic separator,and alunite concentrate containing Fe2O3 1.71% and SO3 28.78% was obtained with a recovery of SO3 82.23%.
