    Lead refining - messergroup

    The aim of lead refining is to produce sellable lead metal. This is done in a refining kettle by separating out unwanted accompanying elements and alloying. After copper has been separated out, arsenic, tin and antimony are removed from the lead melt. The resulting dross is recycled. Kettle for lead refining. Gas Application

    Refining process for removing antimony from lead bullion ...

    During this bullion cleansing process, some of the sulfur reacted with the sodium of the antimony-rich refining dross inherently suspended in the bullion as well as adhering to the kettle walls and some antimony was thereby transferred back into the bullion. The final bullion antimony content, after cleansing, thus was 1.8% by wt. antimony.

    Lead smelting - Wikipedia

    The bullion is agitated in kettles then cooled to 700-800 degrees. This process results in molten lead and dross. Dross refers to the lead oxides, copper, antimony and other elements that float to the top of the lead. Dross is usually skimmed off and sent to a dross furnace to recover the non-lead components which are sold to other metal ...

    Lead processing - Refining Britannica

    Lead processing - Lead processing - Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy. The Parkes zinc-desilvering process is the most widely used ...

    Refining is the treatment of a crude, relatively impure metal product from a metallurgical process to improve its purity and to define its composition better. Sometimes the goal of the refining process is to obtain the metal itself in pure form. However, the goal may also be to produce a mixture with a well-defined composition, as in the ...
