摘要
对软锰矿与黄铁矿、硫酸直接浸取制备硫酸锰进行了实验研究 ,得出了最佳工艺条件。当浸出条件为软锰矿∶黄铁矿∶硫酸为 1∶0 3∶0 4 5 ,浸出温度为 96℃ ,浸出时间 7h ,固液比 1∶5时 ,锰的浸出率可达 97 0 0 %。该工艺具有能源消耗少 ,生产成本低。
The process of proparing manganese from pyrolusite by reductive leaching are studied and the optimum leaching condition is obtained. On leaching conditions as follows pyrolusite∶pyrite∶sulfuric acid ratio is 1∶0 3∶0 45, the leaching temperature 96℃, leaching time 7 h, the solid liqud ratio is 1∶5, leaching Mn percentage of 97 00%. The technology has some advntages, such as saving energy, low production cost and high recovery of Mn.
