我国攀枝花和承德等地区拥有丰富的钒钛磁铁矿资源,早期的选钛以重选和电选为主,大量的细粒钛铁矿损失在尾矿中,TiO2的选矿回收率只有10%左右。自1994年以后,SLon立环脉动高梯度磁选机开始在钛铁矿选矿工业中应用,使细粒级和微细粒级钛铁矿得到了较好的回收。随着SLon磁选机的应用和浮选新技术的发展,我国钛铁矿选矿技术水平得到了迅速的提高,目前选钛生产回收率已可达到40%。然而,我国选钛回收率还有较大的提高潜力,通过优化选矿流程和设备,选钛回收率有可能达到50%~60%,若能在-20 μm钛铁矿选矿技术方面取得突破并从强磁选和浮选尾矿中再选出一部分次钛精矿,则选钛回收率有望达到70%。  相似文献

针对煤矿开采深度不断向深部延伸,掘进巷道受深部高应力的影响越来越大,巷道围岩整体稳定性差,矿山压力显现越剧烈现象,一般锚网喷加锚索支护无法从根本上控制巷道的变形。总结了平煤股份十三矿-685 m进风大巷注浆加固技术,依据对巷道掘进之后变形监测数据的采集,对巷道变形机理进行分析研究,并对注浆时段进行了合理选择,在对巷道的注浆工艺进行了充分论证的基础上,对巷道进行了注浆。注浆后效果表明:巷道滞后注浆时间段的选择非常重要,巷道在恰当的时间内进行注浆加固施工,能有效控制巷道的变形,巷道注浆后变形量明显减小,岩体的稳定性明显增强,减少了巷道日常维修工作,降低了矿井的生产成本,保障了矿井的安全生产。  相似文献
