مصنع لتجهيز البوكسيت/antimony refining from lead
Jan 01 1989 INTRODUCTION The penultimate process for the refining of commercial lead bullion is the removal of bismuth by the EettertonKroll process. This involves the use of calcium and magnesium metals which react preferentially with bismuth and residual antimony to form solid intermetallic compounds on the bullion which may be skimmed. Separation Behavior Of .
The other metal impurities often include antimony and arsenic and is referred to as a 'speiss', which is recovered and sold on for further purifiion. Pyrite is a key material in the lead refining process(1). In addition to primary production, it finds important roles in secondary treatment of smelting wastes and other remediationtype ...
09/05/2019 · Lead refining dross containing plenty of tin and other heavy metals, such as lead and antimony, is considered a hazardous waste generated in large quantities in lead smelter plants. In this study, calcium stannate was synthesized from lead refining dross using sodium carbonate roasting and alkaline leaching followed by precipitation with CaO.
Common lead smelting process usually produces lead bullion containing 24% impurities such as copper, arsenic, antimony, tin, bismuth, indium, silver and gold, etc. Those impurities are valuable metals but have negative effects on lead's functional performance in terms of hardness, toughness and corrosion resistance. The process of lead refining is to improve lead purity .

The refining of crude lead takes place in a refining kettle at temperatures between 400 and 550°C. If only battery scrap is used for lead production, two 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 .
antimony refining from lead The major significant (>70 ppm) impurity in the electrowon lead was antimony; however, it was readily removed when the hode sheets were melted for a final refining and shape casting. The behavior of antimony appears to be related to the formation of pentavalent antimony (up to 3 g Sb 5+ /L in ...
