西藏某碱性低磷硫磁赤混合铁矿选铁试验研究

摘要

Mineral processing technology to recover iron from an alkaline maghemite ore from Tibet with low content of sulfur and phosphorus was investigated. A flowsheet consisting of a grinding, a low intensity magnetic separation and a high intensity magnetic separation was introduced to treat this maghemite ore with a TFe grade of 39. 23% , and a good beneficiation index of a bulk concentrate yield of 48. 86% , a TFe grade of 63.50% and a TFe recovery of 80. 50% , can be achieved.%对西藏某碱性低硫磷磁赤混合铁矿进行了选铁试验研究.采用磨矿-弱磁-强磁选流程处理TFe品位39.23％的磁赤混合铁矿,获得了混合铁精矿产率48.86％、TFe品位63.50％、TFe回收率80.50％的选矿指标.
