Oxidizing Roast; Stibnite the Antimony Mineral
In smelting stibnite ore two processes are available, precipitation and roasting-reduction. The former is suited, only for high-grade ores. As low-grade ores are more common than high-grade, roasting-reduction is of greater importance than precipitation.
Antimony Assay & Determination by Roasting Stibnite
The product obtained by roasting stibnite is likely to contain some unoxidized antimony trisulphide and a mixture of antimony trioxide and antimony tetroxide. It was desired to determine, as accurately as possible, the condition of the antimony as well as the total quantity present.
Stibnite - an overview | ScienceDirect Topics
A two-stage roasting process, similar to that used for arsenic sulfide ores, can also volatilize antimony oxides and prevent adverse reactions such as the production of metallic antimony, which can coat the surface of gold particles (Nagy et al., 1966) or the formation of silver glasses in high-silver ores (Matsukawa and Sakai, 1956).
Sulfur fixation and reduction roasting of stibnite for ...
One kilogram of stibnite was first mixed with a certain amount of carbon and ZnO ash with the optimum ratio according to above experiments, and subsequently, the mixture was roasted at 800 °C for 2 h. This process achieved a high Sb generation of 90.76% and a sulfur-fixing rate of 94.54%.

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 …
