·Current extractive metallurgy techniques for lead refining by the Betts Electrorefining Process BEP are reviewed In the BEP refined lead >% can be produced by the electrorefining of impure lead anodes The process relies on the selective dissolution of lead which leaves behind a strong and adherent layer of solids slimes containing the noble
·Refining using Sulphide of Antimony This process is also some centuries old and is based on the fact that when gold silver alloys are melted with sulphide of antimony sulphide of silver will form and the gold will alloy with the antimony Au 6Ag Sb2S3 = Au 2Sb 3Ag 2S Copper and other metals will also be removed by this process
·Production process generally includes three steps raw material pretreatment smelting and fire refining Raw Material Pretreatment The process is set up to obtain the chemical components and properties most suitable for the next metal extraction or enrichment which includes mineral processing calcination roasting sintering etc Different operations are
·Lead grid from spent lead acid batteries contains significant amounts of tin and antimony In classical pyro refining processes of lead tin oxidizes and is transferred to dross making its recovery problematic and expensive This paper presents an innovative method of pyro refining lead using metallic aluminum and calcium to purify the lead from contaminants

·Spent lead acid batteries have become the primary raw material for global lead production In the current lead refining process the tin oxidizes to slag making its recovery problematic and expensive This paper aims to present an innovative method for the fire refining of lead which enables the retention of tin contained in lead from recycled lead acid batteries
·In light of this it is hoped a new antimony roaster being built in Oman could help diversify supply of the metal away from China which dominates mining and refining especially as the ongoing trade war between the US and the Asian nation intensifies Outlook for antimony China currently accounts for over 90% of antimony supply
·In the process of electrolytic refining the required antimony content of lead anode plate is approximately wt% When antimony content of lead anode plate is more than wt% antimony firmly adheres to the residual lead anode plate during the refining process which leads to difficulty in cleaning
Refining dross is the result of lead refining process where impurities like copper tellurium arsenic antimony tin silver zinc and bismuth in sequence from lead bullion There are many types and composition of each type of dross varies and is subjected to specific refining steps and raw material contents
