Stibnite froth flotation: A critical review - ScienceDirect

Indeed, dextrin has been reported as a depressant for pyrite in the flotation of an antimony oxide ore (Qin et al., 2017). According to Lager and Forssberg (1989b), moderate dosages of dextrin should not affect the flotation of stibnite. Dextrin dosages between 150 and 500 g/t have been reported in some stibnite flotation studies .

Stibnite - an overview | ScienceDirect Topics

Antimony is most commonly found in sulfides and sulfo salts such as boulangerite, jamesonite, stibnite, and tetrehedrite, as well as in some oxides such as semarmontite, stibiconite, and valentinite. Of the more than 100 minerals of antimony that are found in nature, the predominant one is stibnite (Sb 2 S 3 ).

Metallurgy - US Antimony

Metallurgy. 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.
