摘要
本文简述了采用弱磁—强磁—浮选工艺流程选别(?)云鄂博主东矿(?)贫氧化矿综合回收铁、稀土、铌的第二阶段工业分流试验结果,分析讨论了主要怍业的选别效果,认为该工艺流程能较好地全面地回收铁、稀土、铌等有价成分,并为萤石等非金属资源的综合利用创造了较好的条件。
A brief description is presented of the results obtained at the second stage industrial partial flow test of comprehensively recovering iron, rareearths and niobium from low and medium grade oxide ores of the Dong Mining Aera using a process flowsheet of low intensity magnetic separation-high intensity magnetic separation-flotation separation. The authors discuss and analyse separation results of its main operations, concluding that comprehensive recovery of iron, rare-earths and niobium can be achieved using the process flowsheet, and good conditions can be provided for comprehensive utilization of non-metallic resources, such as fluorite.
