2014-6-1 · Antimony, is primarily extracted from antimony sulfide ores, such as stibnite (Lager and Forssberg, 1989a, Lager and Forssberg, 1989b), jamesonite (Lager and Forssberg, 1989a, Lager and Forssberg, 1989b) and as a byproduct in lead smelting. Primary sulfide antimony resources are insufficient to satisfy industrial demand.

2017-6-7 · Antimony trioxide volatilizes easily at higher temperatures. This property is used in different industrial applications such as roasting of sulfidic antimony ores where the anti-mony is separated as trioxide via the offgas due to its high vapor pressure. Production of high-purity antimony triox-ide from high-grade antimony metal is considered state of

2019-1-1 · The composition of the roasting product at 900 °C has shifted to antimony and ZnS, and antimony is spherical. The metal antimony is melted because the temperature is so high, so it is distributed as a spherical particle. The melting point of ZnS is as high as 1975 °C, so it does not melt and exists as a hexagonal crystal.
