摘　　要：文章简要介绍了电解锰尾渣现状,根据尾渣特性制备硫酸钙晶须,探讨不同工艺条件对硫酸钙晶须形貌的影响。在所研究范围内,酸浸锰矿温度为55℃、硫酸的滴加速度为5 mL/min、搅拌速度为150 r/min及保温时间为8 h时得到的硫酸钙晶须形貌最佳。文章为锰矿尾渣资源化利用提供新的发展方向。In this article,the present situation of electrolytic manganese residue is briefly in-troduced.Calcium sulfate whisker is prepared according to the characteristics of the residue.The ef-fect of different process conditions on the morphology of calcium sulfate whisker was investigated.The best morphology of calcium sulfate whisker was obtained when the temperature of acid leaching manganese ore is 55℃,the drop speed of sulfuric acid is 5 mL/min,stirring rate is 150 r/min and soaking time is 8 h.This process provided a new development direction for the resource utilization of residue.
