<p>Method for recovering Cadmium (Cd) and Nickel (Ni) from batteries containing the steps of: a) reducing the size of the batteries to small pieces; b) leaching out the fraction at approximately 90 DEG C; c) removing the Cd; d) stripping the extractant and separating metallic Cd therefrom; e) converting Fe-ions into (solid) Fe hydroxide and filtering this off: f) recovering Ni from the filtrate. After step a) the small pieces are separated into a coarse fraction (linear sizes more than 3 mm) and a fine fraction. The coarse fraction is separated into a magnetic and a non-magnetic fraction.</p> |
