| Abstract: | 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. |
