Vapor pressure. P (Pa) 1 10 100 1 k, The industrial methods for refining antimony are roasting and reduction with carbon or direct reduction of stibnite with iron. The largest applications for metallic antimony are an alloy with lead and tin and the lead antimony plates in lead–acid batteries. Alloys of lead and tin with antimony have improved properties for solders, bullets, and plain,Leaching of Antimony From a Refractory Precious Metals,,key step for removal of the antimony has been an ambient pressure alkaline sulfide leach. In 1990, a comprehensive laboratory study was undertaken to better understand this process. Factors,Separation behavior of arsenic and lead from antimony,,01/05/2020· It could be reduced from 780 ppm to 450 ppm in the residual Sb product even at low temperatures and high pressures (e.g. at 1050 K with pressure of 200 Pa), but its concentration was still too high for the further purification by zone refining. If more reduction of As by using higher temperatures and/or lower pressures is desired, a lower Sb-yield (residue as the product without consideration ofSeparation behavior of arsenic and lead from antimony,,When classifying impurities in commercial pure antimony (Sb, 99.8%), arsenic (As) and lead (Pb) should be brought to the forefront consideration. Due to the known difficulty of As removal through zone refining, it is meaningful to investigate its separation tendency through alternative methodologies such as vacuum distillation, promoted by the large dif-ference of their vapor pressures.
