  • Process for recovering lead from the active material of used batteries
    Patent number: 4030916
    Abstract: Lead is recovered from the lead-containing sludge from used batteries by first heating the sludge at 100.degree. - 150.degree. C to drive off the water. The sludge is subsequently reacted at about 1,000.degree. C with carbon powder in a closed electric furnace. The relatively small volume of water-free waste gas produced leads to a marked saving in energy. Not only dust but also the SO.sub.2 can be removed simply from the waste gases.
