in the EU but closer to the mining location. Re-volatilizing of crude antimony(III) oxide Step 1) Crude stibnite is oxidized to crude antimony(III) oxide using furnaces operating at approximately 500 to 1,000 °C. The reaction is the following: 2 Sb2S3 + 9 O2 → 2 Sb2O3 + 6 SO2 Step 2) The crude antimony(III) oxide is purified by sublimation.
