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

May 01, 2020· The samples before refining were taken from three different positions of the bar (left, middle and right); while the samples after refining were taken from the bottom every 5 cm along the bar (see Fig. 5). This sampling method assures the homogeneity of each bar before refining as well as avoids detecting intermetallic compounds at the top of ...
Metallurgy - Metallurgy - Refining: Refining is the final procedure for removing (and often recovering as by-products) the last small amounts of impurities left after the major extraction steps have been completed. It leaves the major metallic element in a practically pure state for commercial application. The procedure is accomplished in three ways: refining by fire, by electrolytic, or by ...
The formation of metallic antimony occurred without any decomposition in the course of the direct reduction of sodium metaantimonate. The concentrate reduction smelting carried out in presence of a refining flux provided to obtain rough antimony of low impurities content. Keywords: antimony concentrate, reduction smelting, rough antimony.

The refined metal is then ladled out and cast as " star antimony," the surface of the cakes showing a well-defined crystal structure. 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.
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 & Smelting Co. was formed for ...
Lead processing - Lead processing - Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy. The Parkes zinc-desilvering process is the most widely used ...

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 ...
