  • Antimony Recovery from End-of-Life Products

    Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and

  • Lead refining - messergroup.com

    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

  • Lead smelting - Wikipedia

    Lead is usually smelted in a blast furnace, using the lead sinter produced in the sintering process and coke to provide the heat source. As melting occurs, several layers form in the furnace. A combination of molten lead and slag sinks to the bottom of the furnace, with a layer of the lightest elements referred to as speiss, including arsenic and antimony floating to the top of the molten

    02.02.2020· if it's just antimony you can swage it and still retain the softness. you might could use a borate to capture and remove the antimony from the alloy. but to do it at home would take about 30 pounds of borate to clean 15 pounds of lead and quite a bit of time. I don't know how you would remove the arsenic though.

  • Method of refining lead from impurities

    The essence of the prototype is to clean up lead-antimonic alloy in two areas: first, in the melt is injected aluminum or aluminum-magnesium alloys (purification by antimony at this station refining reaches 0.1 percent), then injected magnesium chloride and lead or a mixture of caustic soda and sodium nitrate (antimony content at the end of the refining process is 0.001%).

  • Removing antimony from waste lead storage

    When antimony content of lead anode plate is more than 1.2 wt%, antimony firmly adheres to the residual lead anode plate during the refining process, which leads to difficulty in cleaning. Therefore it must be treated by preliminary pyrometallurgical refining to reduce antimony content before the electrolytic refining, which means long process and more energy consumption.
