Abstract
A method for regenerating raw materials of waste Nickel-Cadmium batteries based on solvent extraction is disclosed. The method is used for disassembling, rinsing and shredding industrial waste from Nickel-Cadmium batteries. The solvent extraction technology is easy for large-scale and continuous production, and valuable metals such as cadmium, cobalt and nickel are extracted from the waste Nickel-Cadmium batteries to prepare products such as cadmium nitrate, cobalt nitrate, nickel nitrate which are directly used for producing raw materials for Nickel-Cadmium batteries. No new waste salt and waste residues are generated in the process. High-efficiency separation and purification of all valuable metals during the regeneration of waste Nickel-Cadmium batteries and the full-life cycle regeneration cycle of Nickel-Cadmium batteries are achieved.
