Antimony Refining Technique

REMOVAL OF LEAD FROM CRUDE ANTIMONY BY USING NaPO .

Reaction mechanism was clarified by using the TGDTA and XRD techniques and single factor experiments of removal lead from crude antimony were engaged. The results show that PbO and NaPO 3 begin endothermic reaction at 863K (590°C), and the reaction mainly form NaPb 4 (PO 4) 3 and NaPbPO 4 below 1123K (850°C) and above 1123K (850°C), respectively. Sb 2 O 3 and NaPO 3 start ....

Antimony and Antimony Compounds

 · Antimony metal is recovered from ore primarily by pyrometallurgical techniques. Because rich ores are becoming rare, greater recourse is being taken to intermediates in processing and metal industries. Hydrometallurgical processing is suitable for some ores containing precious metals and is used by the Sunshine Mining Co. (USA). Refining and fine purifiion techniques are used for ....

Removal of antimony from leadtwo per cent antimony alloy.

A refining technique that received considerable attention in these studies is the use of highmelting point intermetallic compounds to remove small amounts of undesirable impurities from base metal scrap. Once the compound has been formed, separation from the base metal can be achieved by decanting, skimming, or filtering. This article describes a technique for removing antimony from lead by ......
