    Lead processing, preparation of the ore for use in various products. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury). Its low melting point of 327 °C (621 °F), coupled with its easy castability and softness and malleability, make lead and lead alloys especially suitable for a wide range of cast products, including …

    Besides the ore itself, only a few raw materials are necessary for the refining of lead. The ore concentrating process requires pine oil, alum, lime, and xanthate. Limestone or iron ore is added to the lead ore during the roasting process. Coke, a coal distillate, is used to further heat the ore

    The Parkes zinc-desilvering process is the most widely used pyrometallurgical method of refining lead bullion. As in smelting, the lead is first melted and again allowed to cool below the freezing point of copper, which crystallizes and, along with any remaining nickel, cobalt, and zinc, is removed by skimming. The lead mix then passes to a reverberatory “softening” furnace, where the temperature is raised and …

    refining of lead from lead battery recycling - stc italy

    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. It would be more correct to call only the process of antimony, arsenic and tin removing “softening”

    The process of purification of any substance is called refining. Lead refining is no different, except that while refining we do a lot of value addition to the crude ore. In our process of refining we use a Pyrometallurgical process for producing Lead with a purity level of 99.97%
