| 摘 要： | 以低品位的软锰矿为原料,硫酸亚铁为还原剂,对还原浸取锰的工艺条件进行了研究。试验结果得到硫酸亚铁浸取锰的最佳工艺条件:硫酸亚铁和MnO2物质的量之比为2∶1,液固比4∶1,硫酸初始浓度10%,搅拌速度220 r/min,反应温度90℃,反应时间3 h。在该条件下锰的浸出率可达97.12%。

| Abstract: | The technological conditions of ferrous sulfate reductive leaching manganese from low grade pyrolusite were researched. The optimum technological conditions of leaching manganese ore： ferrous sulfate to manganese dioxide molar ratio is 2 ; 1, liquid-solid ratio is 4 to 1, initial acid concentration is 10 %, stirring speed is 220 r/min, leaching temperature is 90 ℃, leaching time is 3 h. According to the technological conditions of leaching manganese, the leaching rate of manganese reaches 97.12 %. |
