Method for recovering valuable metals from waste ternary materials

The invention discloses a method for recovering valuable metals from waste ternary materials. The method comprises the steps of electrode pretreatment, metal ion leaching, metal salt solution preparation and lithium carbonate recovery. According to the method, the valuable metal ions in the ternary materials are recovered through a mixed acid leaching method, and a nickel-cobalt-manganese precursor is prepared; and the method is simple to operate, no reducing agent needs to be additionally added, the cost investment is low, and the metal recovery rate is high. 本发明公开了一种从废旧三元材料中回收有价金属的方法，通过电极预处理、金属离子浸出、金属盐溶液配制、回收碳酸锂。本发明通过混合酸浸法回收三元材料的有价金属离子，并制成镍钴锰前驱体，该方法操作简单，无需额外加入还原剂，成本投入低且金属回收率高。
