2020-11-23 · Refining process for removing antimony from lead bullion ... 10/1/1984 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.
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.

ABSTRACT OF THE DISCLOSURE "An Improved Refining Process for Removing Antimony from Lead Bullion" 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 reverberatory furnace for reduction of antimony oxide was also enlarged: refining at lower temperatures and continuous mechanical casting into ingots gave a high-grade regulus. To enlarge the range of antimony products successful testwork was carried out on a technique characterized by fuel-free, self-oxidation volatilization capable of producing high-quality antimony white from metallic antimony.

2016-4-18 · In summary, this new pyro-refining process for Pb impurity removal from crude Sb is highly effective, and smoke pollution free, compared with the current processes, which caused by the dehydration of AH 2 PO 4 (A = Na, NH 4) and the reactions between antimony and water vapor. Furthermore, this new process can be combined with the existing industrial equipment of the current process.
2017-11-1 · Abstract The fire refining processes for antimony with the objective to primarily remove tin and lead as much as to receive respective residuals of 0.002% and 0.02% in the metal are multistage processes, associated with significant antimony losses during the slag phase, particularly when deep treatment for tin removal.
