Abstract

Process comprises two stage treatment, with intermediate recovery of a lead-silver residue. To increase productivity, basic iron sulphates are pptd. in the second stage, by zinc ferrite through a simultaneous dissolution-pptn. reaction. - In this Patent of addn., the pptn. should be effected at above 90 deg.C and at pH 1-15, with an Fe content exceeding 65 g/l.
