Antimony process - American, Smelting Refining

The process for treating antimonial lead which comprises softening the lead, reducing and smelting the antimony slag therefrom to metal, removing tin and arsenic from said metal, concentrating same into a high antimony product and euitectic metal, treating the high antimony product in a fuming furnace thereby yielding antimony oxide, an antimonial slag and residualRefining 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 entrappedAntimony Smelting - Mineral Processing & Metallurgy,2016-03-18· China now leads the world in antimony production, having contributed during recent years something over 60 per cent, of the world’s production. The history of the antimony industry of China dates back to 1897 when the Tai Shing Co. was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude; and in 1908 the Wah Chang Mining &

Antimony Recovery from End-of-Life Products and

2016-02-08· The antimony recovery rate was 92 %, and a 99.7 % pure antimony oxide distillate was obtained. Binz et al. developed a bottom-up process to recover antimony from lead-refining residues. They investigated a more selective oxidation during lead softening and the carbothermic reduction of the slag to produce a concentrated antimony slag and,Gold parting - Wikipedia,The very earliest attempts at refining gold can be shown by the surface enhancement of gold rings. Gold quality was increased at the surface by 80–95% gold compared to 64–75% gold at the interior found in Nahal Qanah Cave dated to the 4th millennium BC. Further evidence is from three gold chisels from the 3rd Millennium BC royal cemetery at Ur that had a surface of high gold (83%), low silver (9%) and copper (8%) compared with an interior of 45% gold, 10% silver and 4…Antimony Smelting - Mineral Processing & Metallurgy,China now leads the world in antimony production, having contributed during recent years something over 60 per cent, of the world’s production.

When arsenic, antimony and bismuth enter the electrolyte, they can undergo a number of different reactions depending on their concentrations, as well as the presence and the concentration of other elements. Arsenic enters the electrolyte as As(III), and is graduallyLiquation - Wikipedia,Liquation is a metallurgical method for separating metals from an ore or alloy.The material must be heated until one of the metals starts to melt and drain away from the other and can be collected. This method was largely used to remove lead containing silver from copper, but it can also be used to remove antimony minerals from ore, and refine tin

US8211207B2 - Process for refining lead bullion

A unique pyrometallurgical lead refining process includes adding a Lewis acid component and an Arrhenius base compound to a molten lead bullion. The Lewis acid component and Arrhenius base compound are added in stoichiometric amounts that preferentially remove lighter amphoteric elements from the molten lead bullion, and promote reactions with amphoteric p-block elements in the lead bullionUS2335569A - Process for removing antimony from,Process for removing antimony from lead containing it Download PDF Info Publication number US2335569A.

Extraction of Antimony

A method has also been suggested for refining electrolytically using an electrolyte containing antimony trifluoride with about 100 grams of free sulphuric acid and 20 grams of free hydrofluoric acid per litre. Low-grade ores, which generally contain oxidised minerals in addition to sulphides, are first roasted to produce either the non-volatile tetroxide or the volatile trioxide.
