Title:
マンガン及び亜鉛を含有する廃電池からの硫酸マンガン及び硫酸亜鉛の製造方法
Document Type and Number:
Japanese Patent JP5246604
Kind Code:
B2
Abstract:
A method for preparing manganese sulfate and zinc sulfate from waste batteries containing manganese and zinc, and more particularly to a method for preparing manganese sulfate and zinc sulfate from waste batteries containing manganese and zinc. Zinc powder and activated carbon are added to a leached solution obtained from a continuous leaching process so as to remove heavy metals and organic materials from the leached solution, and then the leached solution is spray-dried to simultaneously obtain manganese sulfate and zinc sulfate at high-purity by a simple process without generating wastewater. An environmentally friendly waste battery recycling process is thereby provided, because it is not required to use additional chemical substances for neutralization titration or impurity removal in recovering manganese sulfate and zinc sulfate by leaching a waste battery powder.
