US4425160A Refining process for removing antimony

An improved process for refining lead bullion containing antimony, in which the bullion is initially heated in a refining vessel to about 25° F. (14° C.) above the bullion melting point, and is thereafter kept molten primarily by exothermic process reactions. The process includes the steps of melting the lead-antimony bullion, agitating the bullion, adding caustic soda and metallic sodium to

Refining process for removing antimony from lead bullion

In using aluminum for antimony removal, the refining process is carried out at a temperature of 1300° F. The aluminum, upon addition, melts and is mixed into the bullion to react with the antimony to form an aluminum-antimony intermetallic which rises and is separated from the bullion as a dross. In this process, a considerable amount of lead is also physically entrapped in the dross. In U.S

Refining Process For Removing Antimony

The refining of crude antimony often use Na 2 CO 3 to remove arsenic in the process of antimony smelting . In this study, alkali in arsenic-alkali residue was recovered in the form of NaHCO 3, while NaHCO 3 has the property of being easily decomposed and converted into Na 2 CO 3 by heating (Chen et al., 2017, Hartman et al., 2013). Therefore
