ABSTRACT:
Metallic lead, lead compounds and plastic material are recovered from the remaining inert material in scrap storage batteries by crushing the scrap storage batteries, adding the crushed material to an aqueous suspension of magnetic granular material to separate the inert and plastic material from the metallic lead and lead compounds by suspending in an aqueous magnetic suspension the inert and plastic material but not the metallic lead and lead compounds in said suspension, separating the suspension from said metallic lead and lead compounds, magnetically separating the magnetic granular material from the inert and plastic material and then removing the plastic material from the inert material by floatation in an aqueous media.
