Pb distribution in multistep bismuth refining products

Article

Abstract

Significant amounts of lead impurities have been removed from bismuth using a multistep refining process involving bismuth electrorefining in a hydrochloric acid solution, melting of a cathodic bismuth sponge, and pyrometallurgical processing of molten bismuth in an inert atmosphere. The Pb distribution between bismuth and the products forming in different refining steps has been studied.
