Abstract

FIELD: nonferrous metallurgy. SUBSTANCE: lead-containing waste were treated preliminary with solution at pH = 6.0-7.0 followed by sulfur acid leaching, carbonization and thermic treatment at 200-600 C and reduction is carried out at 700-800 C. Method is used for lead and other nonferrous metal-containing waste processing. EFFECT: improved method of processing.
