The refining of crude lead takes place in a refining kettle at temperatures between
400 and 550Ã‚°C. If only battery scrap is used for lead production, 2 subsequent refining steps are required:
1. Removal of Cu which might have entered the melts through copper wires.
2. Removal of antimony originated from the former grid metal to produce pure lead
While the removal of Cu is done in adding elementary sulphur, Sb can be removed by selective oxidation or by adding sodium nitrate (NaNO3). The lead in the kettle is stirred and a dross formed. The impurities are now removed from the melt by Skimming of the dross formed. It is obvious that the success of the refining has to be controlled by chemical analysis. The refined metal is cast into ingots for shipment, sale or further manufacturing.
Refining pot/Alloying must be manufactured in boiler steel using 32mm to 46mm.
