摘要贵州省有大量的鲕状赤铁矿，但用传统的选矿方法难以利用。研究了贵州鲕状赤铁矿的H2还原反应。采用光学显微镜、X射线衍射和化学分析等方法，对不同还原条件下的矿石显微结构、物相变化和成矿率进行了表征。随着还原时间的延长，还原样品的金属化率增加。当还原温度为1000°C，还原时间为120 min时，金属化率可达80.75%，还原过程中可生成FeAl 2 O 4和Fe 2SiO 4等新相，阻碍了鲕状赤铁矿的还原。
Abstract Oolitic hematite abounds in the Guizhou Province of China but is hard to use with the traditional process. The reduction of Guizhou oolitic hematite by H2 was studied. Ore microscopy, phase change, and the metallization rate of oolitic hematite under different reduction conditions were characterized by optical microscopy, X-ray diffraction, and chemical analysis, respectively. The metallization ratio of the reduced sample increased with the increase of reduction time. The metallization ratio reached 80.75% when the temperature was 1000°C and the reduction time was 120 min. The new phases of FeAl2O4 and Fe2SiO4 can be generated during the reduction process, which hindered the reduction of the oolitic hematite.
