Abstract
The present disclosure relates to a method for recovery of valuable metals and a zeolite-containing material from a waste cathode material reaction vessel, in which valuable metals and a zeolite-containing material are recovered from a waste cathode material reaction vessel being discarded, and recycled as resources, thus reducing waste from the waste cathode material reaction vessel.
Claims27
A method for recovery of valuable metals and a zeolite-containing material from a waste cathode material reaction vessel, comprising:
- (a) recovering a nickel·cobalt·manganese (NCM) precursor from the cathode material powder remaining in a waste cathode material reaction vessel;
- (b) preparing lithium hydroxide from a washing solution (I) of the waste cathode material reaction vessel;
- (c) sulfating the residue remaining after separating the washing solution (I) in step (b) to prepare lithium carbonate from a washing solution (II);
- and
- (d) preparing a zeolite-containing material from the residue remaining after separating the washing solution (II) in step (c).
