  • Refining process for removing antimony from lead bullion

    He also contemplates antimony removal during the refining process to remove most of the antimony due to the fact that where arsenic and antimony content of the lead is above about 002% by weight, relatively large quantities of antimony as well as arsenic are incorporated into the tellurium during the detellurizing procedure The sodium or potassium or mixtures thereof are incorporated in theThis process involves dipping the ascast metal in sulfuric acid of 175 sp gr This treatment it is claimed will remove antimony from a surface layer of at least 10 c mm thickness of alloy The work described below for removing surface antimony from antimonial lead differs from that deRemoval of Surface Antimony from Antimony Lead Alloys byThe invention relates to a process for removing tin, arsenic and antimony from molten lead by means of oxygen or oxygencontaining gas mixtures, which is or are blown into the molten lead by means of at least one gas nozzle (2) To avoid damage to the gas nozzle, at least the oxygen outlet region (13) thereof, located in the molten lead (6), is enveloped by an inert gasUSA Process for removing tin, arsenic and

    A unique pyrometallurgical lead refining process includes adding a Lewis acid component and an Arrhenius base compound to a molten lead bullion The Lewis acid component and Arrhenius base compound are added in stoichiometric amounts that preferentially remove lighter amphoteric elements from the molten lead bullion, and promote reactions with amphoteric pblock elements in the leadThis process involves dipping the ascast metal in sulfuric acid of 175 sp gr This treatment it is claimed will remove antimony from a surface layer of at least 10 c mm thickness of alloy The work described below for removing surface antimony from antimonial lead differs from that deRemoval of Surface Antimony from Antimony Lead Alloys byFor the treatment of leadantimony 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 treatmentExtraction of Antimony
