| description | PROBLEM TO BE SOLVED: To separately recover a cathode and an anode material powders with high purity by separately recovering a cathode and an anode material powders from electrode material powders separated from powdered mixture of pulverized substances of a secondary battery by a plurality of thin flow sorting means and repeatedly carrying out separation operation of a slurry in one electrode material side in which the other side electrode material is mixed. SOLUTION: After films are removed from pulverized substances of a battery, an electrode material slurry 26 is produced and the electrode material slurry 26 is treated by thin flow sorting by thin water flow 21 by thin flow sorting apparatuses T1 -Tn to be separated into a cathode and an anode materials 29, 30. In such a thin flow sorting system, a layer flow of an anode material powder slurry 27a with, for example, 100% purity is recovered by respective thin flow sorting apparatuses T1 -Tn and the obtained anode material powder slurry 28a is led to a wastewater treatment tank 17 and on the other hand, a layer flow in the cathode material side containing the remaining anode material 30 is recovered and successively supplied to the thin flow sorting apparatus T2 -Tn connected in series in the next stages. The thin flow sorting treatment is repeatedly carried out until the anode material 30 is completely removed in the thin flow sorting apparatus Tn in the final stage. |
