Kinetics of stibnite (Sb2S3) oxidation at roasting temperatures
Journal of Mining and Metallurgy, Section B: Metallurgy, 2014 Experimental work on the oxidation of stibnite (Sb2S3) was carried out at temperatures between 350 and 500?C and oxygen partial pressures between 1.01 and 21.28 kPa by using a thermogravimetric analysis method. The oxidation rate of stibnite was significantly influenced by both temperature and partial pressure of oxygen.
