Extraction of Antimony - Element Antimony, Sb, Metalloid

The volatilisation and oxidation of antimony trisulphide have been studied in detail. From the results it is suggested that rich or concentrated ores which do not contain precious metals, arsenic or lead should be roasted to antimony tetroxide, while poorer ores, and ores containing precious metals, should be roasted to antimony trioxide.

Beneficiation of Antimony Oxide Ore: A Review

In contrast, gravity separation of antimony oxide ores is difficult. The main difficulty is that the hard-ness of antimony oxide ore is lower than other metal ores, and it is easily overcrushed. In addition, gravity has a limited effect on the selection of fine-grained antimony oxide ore. During flotation of antimony oxide ore, the main
