How to Make Lead from Galena Concentrates - 911

2017-11-16  Lead extraction was 96 pct when galena concentrates were leached in recycled waste fluosilicic acid using hydrogen peroxide and lead dioxide as oxidants. After solid-liquid separation to obtain the lead-fluosilicate solution and the residue containing elemental sulfur, pure lead metal was electrowon in a 20-liter cell containing four titanium anodes coated with lead

Lead: smelting, producing and classification-Metalpedia

A major and primary Lead mineral is galena (PbS) which comprises of 86.6% of lead. In order to smelt this mineral, a blast furnace is needed to be used. A blast furnace is an enormous oven which is used to accomplish the smelting processes. The process in which galena is smelted requires two important chemical reactions to occur within the furnace.
