New process recycles magnets from factory floor
Science Daily GeologyA new recycling method recovers valuable rare-earth magnetic material from manufacturing waste. The process, which inexpensively processes and directly reuses samarium-cobalt waste powders as raw material, can be used to create polymer-bonded magnets that are comparable in performance to commercial bonded magnets made from new materials. It can also be used to make sintered magnets (formed by pressure compaction and heat).
