By using silica aluminum-based cementitious material,electrolytic manganese residue from an electrolytic manganese plant was solidified.The leaching toxicity of solidified electrolytic manganese residue in different curing periods was studied.Through dynamic leaching experiment,the effects of curing time and pH value on the leaching properties of solidified electrolytic manganese residue were researched.At the same time,by applying SEM and XRD,the morphology and composition of solidified electrolytic mangan...
