Abstract
An apparatus for recovering lead from worn out electric storage batteries in which finely divided dried battery mud is injected into a stream of air through the veni contracta of a venturi in an air conduit. A reducing gas and oxygen are successively introduced into the stream through apertures in the walls of the conduit communicating with annular chambers in fuel and oxygen manifolds surrounding the conduit in sufficient quantities to maintain a stable reducing flame. The droplets of metallic lead and slag which fall from the reducing flame are collected in a refractory lined chamber and separated in a conventional manner.
