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

Lead Refining, Lead Recycling, Battery Lead, Crude Lead

The objective of the refining process is to remove almost all copper (Cu), antimony (Sb), arsenic (As) and tin (Sn), since soft Lead are not allowed to have more than 10g per ton of these metals. Pyrometallurgical Refining . Pyrometallurgical Refining is performed in liquid phase, which means that the crude Lead must be melted to temperatures

Process Description. 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.
