摘　　要：在分析富锰渣性质及浸取机理的基础上,本文研究了富锰渣湿法浸取硫酸锰的影响因素。其间通过分析单因素条件试验结果,确定了富锰渣的硫酸浸出最佳条件。简单来说,酸矿比为0.9 g/g,浸出温度为90 ℃,浸出时间为90 min,液固比为10 mL/g。优化条件下,锰的浸出率超过95%,能够很好地实现富锰渣中锰的湿法提取分离。On the basis of analyzing the properties and leaching mechanism of manganese-rich slag,this paper studies the factors affecting the wet leaching of manganese sulfate from manganese-rich slag.The optimum condition of sulfuric acid leaching of manganese-rich slag is determined by analyzing the results of single factor test.In short,the acid ore ratio is 0.9 g/g,the leaching temperature is 90 ℃,the leaching time is 90 min,and the liquid-solid ratio is 10 mL/g.Under the optimized conditions,the leaching rate of manganese exceeds 95%,which can well realize the wet extraction and separation of manganese from manganese-rich slag.
