Lead smelting - Wikipedia

Plants for the production of lead are generally referred to as lead smelters. Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates.

Refining of lead from lead battery recycling - STC Italy

Refining of lead from lead battery recycling The pyrometallurgical Lead refining process is one of the most important procedures of lead battery recycling. This process is also known as “Softening of Lead” because the metal is softened after the removal of some impurities which are present in the raw lead coming from lead battery recycling.

Refining Primary Lead by Granulation–Leaching–Electrowinning

The major significant (>70 ppm) impurity in the electrowon lead was antimony; however, it was readily removed when the cathode sheets were melted for a final refining and shape casting. The behavior of antimony appears to be related to the formation of pentavalent antimony (up to 3 g Sb 5+ /L in HBF 4 ), which was not amenable to purification by cementation.

Extraction of Antimony - Element Antimony, Sb, Metalloid

For the treatment of lead-antimony alloys the Harris process is largely employed in England and some other countries. In this process the scrap metal is melted with an oxidising alkaline flux. Arsenic, antimony and tin are then removed by skimming as sodium arsenate, antimonate and stannate. The sodium antimonate is separated from these by lixiviation, and is reduced to antimony by treatment ...
