antimony, tin, and arsenic are removed. Next, gold and silver are removed by adding zinc. The lead is then refined by vacuum removal of zinc. Refining continues with the addition of calcium and magnesium, which combine with bismuth to form an insoluble compound that is skimmed from the kettle. In the final step, caustic soda,

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.

Facts about the Elements: Antimony. We continue to review some of the most important materials in heat treatment and metallurgy. Antimony is a brittle, bright, shiny metalloid. Metalloids have properties of both metals and nonmetals and are electrical semiconductors. As such, antimony is a weak conductor of heat and electricity.

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 duration, and the ...

The reverberatory furnace for reduction of antimony oxide was also enlarged: refining at lower temperatures and continuous mechanical casting into ingots gave a high-grade regulus. To enlarge the range of antimony products successful testwork was carried out on a technique characterized by fuel-free, self-oxidation volatilization capable of ...

Antimony oxide is a white powder and is derived from the mineral stibnite (antimony sulfide) or produced by the oxidation of antimony metal or as a byproduct of the refining or antimonial-lead alloys. It sometimes behaves as a metal and sometimes as a non metal. In the glass industry small percentages of antimony oxide are used to remove ...

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 ...

Refining and alloying operating temperatures range from 320 to 700°C (600 to 1300°F). Alloying furnaces simply melt and mix ingots of lead and alloy materials. Antimony, tin, arsenic, copper, and nickel are the most common alloying materials. Refining furnaces are used to either remove copper and antimony for soft lead production, or

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;
