Beschreibung
Zusammenfassung:	The invention discloses a valuable metal recovery method, and belongs to the technical field of waste battery recovery treatment. The method comprises the following steps: mixing the positive electrode material of the waste lithium ion battery, a leaching agent and a reducing agent, and leaching to obtain a leaching mixed solution; and carrying out solid-liquid separation on the leaching mixed solution to obtain a valuable metal leaching solution. The method solves or at least partially solves the technical problem of high process cost of valuable metal recovery of conventional waste batteries. 本申请公开了一种有价金属回收方法，属于废旧电池回收处理技术领域。方法包括以下步骤：将废旧锂离子电池的正极材料、浸出剂以及还原剂混合并进行浸出，得到浸出混合液；对所述浸出混合液进行固液分离，得到有价金属浸出液。本申请解决了或至少部分的解决了常规的废旧电池的有价金属回收存在工艺成本较高的技术问题。
