Recovery of Antimony: A Laboratory Study on the Thermal
Antimony is typically classified as a volatile heavy metal, and low-grade ores are commonly produced by pyrometallurgical methods [20]. Industrially, reduction of antimony oxide to metallic antimony is achieved by heat-ing and the addition of carbon in a reverberatory furnace. Volatilization of antimony can be reduced by the addition

Antimony
Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl.

How to Remove Arsenic, Antimony & Bismuth from Copper
The elimination of arsenic and antimony in this operation is considerably greater than that of bismuth. In the case of slags produced from blast-furnace practice, smelting similar materials, I have never found more than 0.015 per cent, of arsenic, and only traces of antimony.

Efficient Bath-Smelting Reduction of Antimony Oxide in FeO
An FeO-SiO2-CaO-Na2O quaternary slag with low melting point was developed for the bath-smelting reduction of Sb2O3. First, the optimum composition of the designed slag was determined through practical experiments to be 36.2% FeO, 31.9% SiO2, 12.0% CaO, and 20.0% Na2O, such that FeO/SiO2 was 1.14.
