摘　　要：为探讨回转窑直接还原条件下，鲕状赤铁矿石的直接还原以及不同还原方法对鲕状赤铁矿直接还原磁选指标的影响，本文分别采用固定床法和流动床法，其中包括内加热法和外加热法对贵州赫章鲕状赤铁矿石进行了直接还原磁选试验，并对过程进行了热力学分析。试验结果表明，采用固定床或外加热流动床法可获得较好的选别指标。To investigate the effects of the direct reduction in revolving kiln and the different reduction methods on the direct reduction magnetic separation performaces of olitic hematite ore,the fixed bed method and the fludizing bed methods which include inner heating or outer heating method were used in the direct reduction magnetic separation tests on Hezhang olitic hematite ore in Guizhou.The test results showed that better separation index could be obtained by the fixed bed method or outer heating fludizing bed method.
