攀西地区选钛厂对磨矿产品中难处理的-0．038 mm粒级(现场习惯称超细粒级钛铁矿)普遍按矿泥抛弃。为提高资源的利用率，对该地区某选矿厂-0．038 mm占95%、TiO2含量为8．80%、有害元素硫含量为0．62%的脱泥产品进行了选矿试验。结果表明，试样采用1次粗选、中矿再选的悬振锥面选矿机重选流程预富集钛，重选精矿1段浮选脱硫，脱硫产品1粗3精1扫、中矿顺序返回浮选流程选钛，最终获得了TiO2品位为47．01%、回收率为28．58%的钛精矿。可见，悬振锥面选矿机重选—浮选工艺可实现超细粒级钛铁矿的高效回收。

Grinding products with particle size of -0. 038 mm(usually being called ultra fine ilmenite) are usually dis-carded as slimes in titanium concentrator in Western Panzhihua area. To more efficiently utilize the resource,beneficiation ex-periments were conducted on the deslimed products in this region with particle size of 95% -0. 038 mm,TiO2 content 8. 80%, and harmful element sulfur content 0. 62%. The results showed that:through pre-concentration of one roughing,middlings re-processing by gravity separation using suspension vibration cone separator,desulfurating by one-stage flotation on the gravity concentrate,and titanium concentration by one roughing,three cleaning,one scavenging and middlings back to the flowsheet in turn process to deal with desulfurated products,titanium concentrate with TiO2 grade of 47. 01% and the recovery rate of 28. 58% were obtained. Therefore,the process of gravity separation by the hanging vibration cone concentrator-flotation can realize the efficient recovery of ultra fine ilmenite.
