An integrated hydrometallurgical route for recycling SmCo magnets from production waste

Year: 2026

Type: article

Abstract: An integrated process recycles SmCo production waste, retaining over 93.5% of Cu in the leaching residue. Sodium–samarium double sulfate reached 99.7% purity, with 99% Fe removal and a pure cobalt solution containing less than 10 ppm impurities.
