摘要
The invention relates to a process for the preparation of positive or negative active mass of lead accumulators by using the active mass separated from production-refuse plates and/or the active-mass wastes produced during production. According to the invention when positive active mass is prepared then positive active mass, while when the negative active-mass is prepared then negative active-mass, previously dried and heat-treated at a temperature of 500 DEG to 600 DEG C. and optionally ground, is fed into a lead-powder producing mill, together with metal lead, in an amount of at most 80% by mass calculated for the mass of the metal lead, and the product thus obtained is led into the plate production.
