ABSTRACT:
The present invention relates to an improved process for producing lead oxide in a pure state from a spent paste resulting from exhausted acid batteries. The spent paste is first calcined and desulfurized, then leached by a concentrated solution comprising an alkali hydroxide at a temperature above 100.degree. C. The separated solution is contacted with a ketone resulting in a suspension from which the .alpha.-lead oxide constituent is recovered. The solutions of alkali and ketone are recycled in the process. The preferred alkali constituents are selected from sodium hydroxide or potassium hydroxide, preferably containing also a small amount of sulfate of the respective alkali metal of the hydroxide used.
