other metal sulfides), which rises to the top, and speiss (high in arsenic and antimony content) are both typically forwarded to copper smelters. The third and final phase in the processing of lead ore to metallurgical lead, the refining of the bullion in cast iron kettles, occurs in 5 steps: (1) removal of antimony, tin, and arsenic; (2) removal
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 …

The antimony process is the same but uses stibnite (Sb 2 S 3) instead of sulfur because stibnite is stable at a higher temperature than sulfur. This is much quicker than the salt process and gave a purer gold, but it could dissolve some of the gold as well. ... Chapter 34–7, Future developments in dorè refining. 613 Edited by Mike D. Adams.
10%A significant number of works are devoted to developing more efficient methods for fire refining antimony from lead [7–13]. In the case of refining rough antimony using phosphorus compounds, antimony can be purified from lead, tin, and iron simultaneously. However, phosphorus compounds are not suitable for refining from arsenic.
A minor amount of antimony is also extracted in countries such as Bolivia, Kyrgyzstan and South Africa. Amounts of antimony are also extracted as a by-product of gold and base metal refining in Australia, Peru, Mexico, Canada and the United States. There is currently no primary extraction of antimony ores and concentrates in the EU.
Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3.
Zhang Xiaoxin et al. treated commercial pure antimony (99.8%) by vacuum distillation-zone refining and achieved good results. Li Liang et al. [ 21 ] used vacuum distillation technology to treat lead anode slime with high antimony content, and crude antimony with a purity of 95.2% could be obtained after two distillations.

fore undergoing refining operations. During drossing, the bullion is agitated in a drossing kettle and cooled to just above its freezing point, 370°–425°C (700°–800°F). A dross composed of lead oxide, along with copper, antimony, and other elements, floats to the top and solidifies above the molten lead. The dross is removed and
