| 摘 要： | 对低品位软锰矿还原浸出工艺进行了研究, 以铁屑作为还原剂, 在硫酸存在的条件下还原浸出软锰矿。通过单因素实验确定软锰矿铁屑还原浸出的最佳工艺条件为:铁屑与软锰矿质量比(简称铁矿比)为0.25∶1, 酸矿质量比为1∶1, 液固比为5∶1, 反应时间为1 h, 初始反应温度为10 ℃。在最佳浸出工艺条件下, 软锰矿中锰的浸出率达到98%以上。

| Abstract: | Studies on reduction leaching technology of low-grade pyrolusite were carried out.Scrap iron was used as reductant to leach low-grade pyrolusite in sulphuric acid.The optimum technical conditions of leaching pyrolusite by single-factor test were confirmed as follows: the mass ratio of scrap iron to pyrolusite was 0.25∶1,the mass ratio of sulphuric acid to pyrolusite was 1∶1,the liquid-solid ratio was 5∶1,reaction time was 1 h and initial reaction temperature was 10 ℃.The leaching rate of manganese in pyrolusite reached above 98% under the optimum leaching conditions. |
