The lead refining technology with separate production of Sn-oxides and As-Sb slags has been developed and is being successfully used. The Sn-oxides are remelted with a reducing agent, the Sn-alloy is purified first by vacuum distillation, and then the fire quality refining of Sn is carried out. The As-Sb-slags are washed from arsenic and leached with sulfide solutions; the antimony is precipitated from the obtained solutions by electrolysis and refined.
