Beschreibung
Zusammenfassung:	A method for preparing a pretreated product for recovering valuable metals of a lithium secondary battery comprises the steps of: preparing a cathode active material mixture from a cathode of a lithium secondary battery; drying or grinding the cathode active material mixture; and classifying the dried or ground cathode active material mixture so that the average diameter (D50) thereof becomes 400 µm or less. Flowability can be increased by decreasing the average diameter before reduction.
