Abstract

The invention discloses a waste lithium battery copper-aluminum separation method and system. The method includes the steps: crushing a waste lithium battery to obtain crushed mixture; screening the crushed mixture for the first time, performing magnetic separation and separating iron in the mixture; screening the mixture after magnetic separation for the second time, performing air classificationand separating nonmetal materials in the mixture; heating copper-aluminum mixture after air classification and realize copper-aluminum separation. By the aid of the technical scheme, copper and aluminum in waste lithium batteries can be efficiently separated and secondarily recycled.

Description

technical field [0001] The invention relates to the technical field of copper-aluminum separation, in particular to a method and system for separating copper and aluminum of waste lithium batteries. Background technique [0002] Batteries are a necessity for electronic devices and are indispensable in the production of life today and in the future. Such as mobile communication equipment such as mobile phones, environmentally friendly electric buses, etc., the increasing development of these industries promotes the continuous innovation of waste lithium battery recycling technology. [0003] The production and use of batteries in my country account for a large proportion in the world. So far, the application speed of lithium batteries in the market has gradually accelerated, and even completely replaced lead-acid batteries and nickel-metal hydride batteries in the field of consumer electronics. Therefore, the recycling and reuse of used lithium batteries is needed by the en...
