以湘西某电解金属锰厂的电解金属锰渣为原料，在分析其浸出特性的基础上，研究硫化钙焙砂固化工艺对电解金属锰渣中重金属离子浸出率的影响。结果表明，利用硫化钙焙砂能有效地固定锰渣中的重金属，固化体浸出液中的重金属浓度明显降低。当硫化钙焙砂用量为电解金属锰渣质量的15％，固化反应时间为3．0 h 时，固化后电解金属锰渣的浸出毒性符合相关国家标准。

Based on an analysis of leaching characteristics of electrolytic manganese residue (EMR)generated in an EMM company in Xiangxi of Hunan province.EMR was immobilized by CaS.The optimal conditions for immobilization process were studied.The results show that the heavy metals in the EMR can be effectively immobilized,when the dosage of CaS was 15% of EMR and the solidification time was 3.0 h.And the leaching toxicity of the amended EMR can meet the requirement stipulated in corresponding national standards.
