In the method the ground scraps are screened to separate the pole active material, i.e. Pb and PbO2, as fines. This active material is then reacted in the presence of a strong alkaline solution to yield a minium precipitate. Minium may be subsequently treated with an appropriate acid, such as fluoboric acid, freed of antimony by precipitating the latter with metal lead, and then subjected to electrolysis to recover lead.
