Abstract

A method for manufacturing and refining crude lead from arsenic-containing lead raw-materials of a metallic, oxidic, sulphatic or sulphidic nature. In the manufacture of said crude lead, the lead raw-material is melted in a furnace in which strong turbulence can be created in the contents thereof, in the presence of a slag former, whereafter the slag is tapped-off. The furnace used is preferably a top blown rotary converter or a furnace of the Kaldo-type. The invention is characterized in that iron in metallic finely-divided form, such as iron filings, iron powder or finely-divided pieces of iron, is charged to the crude-lead melt whilst creating strong turbulence therein, or said iron is caused to be formed in situ, preferably by adding silicon, silicides, carbon, carbides or ferro-alloys containing carbon and silicon, wherewith arsenic and any antimony present form an iron speiss which is separated from the crude-lead melt in liquid form in direct conjunction with a gravitational separation of speiss and crude lead. Any copper present in the melt can be segregated therefrom as metallic copper or a copper speiss, by cooling the crude-lead melt.
