受稀土元素价格上涨和货源不稳定影响,日本在减少稀土元素用量、从废料及废弃磁体中回收稀土元素等方面取得很大成效,例如烧结磁体工厂2013年的稀土元素回收率达到99.8%。目前,从装有烧结磁体的设备回收稀土元素的工作已在进行。过去日本每年稀土类材料用量约为1万t,而通过节省和回收稀土元素 Due to the price increase of rare earth elements and the instability of supply, Japan has made great achievements in reducing the amount of rare earth elements used and recovering rare earth elements from scrap and abandoned magnets. For example, the recovery rate of rare earth elements in 2013 was 99.8%. At present, the work of recovering rare earth elements from equipment equipped with sintered magnets is under way. In the past, the annual amount of rare earth materials used in Japan was about 10,000 t. By saving and recycling rare earth elements
