Mineral processing techniques have been suggested for the recovery of nickel-based alloys from spent batteries. The process involved hammer milling, magnetic separation, knife milling, a second and a final magnetic separation, and size separation. The AB 5 alloy type from Ni–MH batteries can be used as an alloy in stainless steel.

Magnetic Separation Technology For A Recycling Industry

Jun 25, 2019· Steel and iron are the most recycled materials in the world due in part to the opportunity to recover large structures as well as the ease of reprocessing. The use of magnets in the sorting process enables recyclers to easily separate them from the mixed waste stream. Every year, around 400 million tons of metal are recycled worldwide.
