TY - PAT TI - Apparatus and methods for recovery of lead oxide from production and application wastes of lead storage battery production or of lead storage batteries themselves. Verfahren und Anordnung zur Rueckgewinnung von Bleioxyd aus Produktions- und Anwendungsabfaellen der Bleiakkumulatorherstellung beziehungsweise der Bleiakkumulatoren AB - For reasons of economy and pollution control, aqueous lead-oxide-containing wastes from the various steps of lead storage battery production are reprocessed involving e.g. a vibrating screen for separating foreign matter and particles larger than 0.2 mm, dewatering of the residual paste by centrifuging for recycling the thickened product to the production process at an H/sub 2/O content of some 20 wt%. Largish particles separated by the screen can be re-used after being finely ground; the water may be recycled just as well or be discharged following neutralisation.
