摘要

The present invention relates to the technical field of battery recycling,particularlythe recovery of battery active materials from lead-acid battery scrap. Theinventionincludes a method in which battery pulp or battery paste is suspended in waterandat least one froth flotation operation is performed on the suspension toseparateand recover battery active material such as carbon and lead dioxide.
