<p>A process is described for treating spent batteries of any type, comprising essentially the following stages: a) disintegrating the spent batteries followed by stirring in water, then screening to obtain a pulverulent aqueous turbid fraction (underscreen fraction) and a coarse fraction (overscreen fraction); b) stirring the pulverulent aqueous turbid fraction at a pH exceeding 7, followed by filtering by which the solids are separated from the aqueous solution, which is fed to water treatment; c) removing mercury both from the coarse fraction of point a) and from the separated solids of point b) in a mercury removal furnace to obtain residues essentially free of mercury. a</p> |
