Lagging material and the method of recovering the non-magnetic metal piece to use the lagging material to be introduced to the network under the air chamber type wet specific gravity sorter

摘要

PROBLEM TO BE SOLVED: To provide a new ragging material having various useful uses, and to provide a method for enabling an effective recovery of a nonmagnetic metal piece of being so far difficult, by using this ragging material.;SOLUTION: A ragging material (10) is formed by kneading magnetic stainless powder (14) in a granular base material (12), and is provided to be inputted in an under-net air chamber type wet specific gravity sorter. This ragging material may be formed by forming magnetic stainless steel in a grain shape.;COPYRIGHT: (C)2014,JPO&INPIT
