煤基还原贫菱铁矿冶炼海绵铁的实验研究

An Experimental Research on Coal base Reducing Poor Siderite to Sponge Iron

在实验室的系列研究表明：采用固定床罐式法煤基还原贫菱铁矿，得到高金属化率的还原矿，经球磨磁选得到ＴＦｅ＞８０％，ＳｉＯ２＜６％的海绵铁（铁粉）。从而为开发利用低品位矿提供了理论依据。

A series of experiments were carried out in the department laboratory and showed that using fixed bed jar method the coal base reduction of poor siderite can produce reduction ore.by ball milling and magnetic separation the sponge iron(TFe>80%,SiO 2<6%) was obtained.Thereby the scientific basis for developing and utilizing the low grade siderite were provided.
