  • Method and system for reclamation of battery constituents
    Patent number: 8807466
    Abstract: In a method of reclaiming constituent components of sealed batteries, the batteries are initially ground to form a ground feedstock. The ground feedstock is heated to form a dried feedstock. The dried feedstock is screen separated into a coarse fraction and a powder fraction, the coarse fraction including a magnetic fraction and a non-magnetic fraction. The coarse fraction and the powder fraction are further vibratorily segregated. The magnetic fraction may be magnetically extracted from the coarse fraction, while the powder fraction is outputted.
    Type: Grant

    Date of Patent: August 19, 2014
    Assignee: Raw Materials Company Inc.
