Abstract
Disclosed are a wet sorting process for a waste lithium battery and application thereof, which belong to the field of battery material recycling. The wet sorting process includes the following steps of carrying out wet ball milling on a sorting material of a waste lithium battery to obtain a ball-milled product, screening the ball-milled product to obtain a coarse-grained screened material, a medium-grained screened material and a fine-grained screened material, carrying out wet ball milling, screening, magnetic separation and table concentration on the medium-grained screened material to obtain copper, aluminum and a steel shell, and carrying out flotation, magnetic separation and table concentration on the fine-grained screened material to obtain cathode material powder, graphite, copper and aluminum.
