A method for the extraction of antimony from stibnite was first described c.1600 by Basilius Valentinus.To obtain high-purity antimony, zone refining is carried out in an atmosphere of inert gas, or antimony is obtained from previously purified antimony trioxide or antimony trichloride.

Refining Blister-Copper. The elimination of arsenic, antimony and bismuth in the preceding operations has, unless the materials under treatment are uncommonly impure, left only small amounts of these metals in the blister-copper. Their elimination during the refining operation probably takes place entirely by scorification.

Antimony trisulfide with melting point as high as 566°C was prepared by zone refining in sealed quartz ampoules. The deviations from the stoichiometry in the vicinity of Sb 2 S 3 composition were checked by DTA measurements. Some electrical and optical properties of …

The main purpose of this study was to separate lead from crude antimony through an oxidation pyro-refining process and by using sodium metaphosphate as a lead elimination reagent. The process parameters that will affect the refining results were optimized experimentally under controlled conditions, such as the sodium metaphosphate charging dosage, the refining temperature and …

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 ...

Note: Total caustic added was 2.5 lbs. Total refining dross skimmed was 28.3 lbs. From this example, the following observations were made: (a) As seen in Table 2, the first sodium addition results in a low ratio of antimony removal for a pound of sodium added since most of the sodium added in this step goes into solution in the bullion and thus is not available for the antimony removal reaction;
