the antimony losses in the form of antimonate sodium compounds. The refining agent pre-dewatering decreased the evolution of gases during refining and the loss of antimony with gases. The certain amount of refining reagent or flux was added to 200 g of crude antimony containing 3.46% of lead and 1.48 % of tin. The mixture was placed

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 xide, Sb 2 O 3.

Refining and fine purification techniques are used for production of pure antimony metal. There is growing demand for extremely pure antimony. Antimony oxide is being used as flame retardant in increasing quantities. Antimony is a component of many lead and tin alloys, which are important materials for making bearings and solders.

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 ...

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 …

oxide vapors. The vapors are condensed to generate antimony oxide powder. A baghouse is used to recover product in the off-gas. The antimony oxide powder is then blended, classified and bagged for shipment. The crude antimony oxide comes either from off-site or is reclaimed from secondary materials from within the facility.
