The ore is dissolved in hot, concentrated acid and passed over a reducing agent so that all the antimony is in the form Sb3 (aq). The Sb3 (aq) is completely oxidized by an aqueous solution of BrO3– (aq).

LIQUATION: Liquation is the melting of stibnite into “crudum” or “needle antimony”. It is carried out between 550 and 600 degrees C. If the temperature is lower, the recovery is poor. If the temperature is any higher, the stibnite volatilizes into oxide. This method is used to upgrade low-grade ores. The ore is placed on Metallurgy Read More »

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.

06-02-2017· Arsenic, antimony and bismuth are more uniformly diffused in coarse metal than in the ore, where they occur in separate intermixed minerals.
