Oxidizing Roast; Stibnite the Antimony Mineral

09-04-2017· Oxidizing Roast; Stibnite the Antimony Mineral. The leading antimony mineral is stibnite. 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.
