- Primary ore is Stibnite
Hazards
Production
Extraction
The primary ore of antimony is Stibnite, Sb2S3.
roast/reduce
Stibnite, roasted in air, converts to antimony trioxide, which can be carbothermically reduced.
binary salt
It is possible to directly reduce stibnite to antimony in a molten salt bath [1]
Purification
Testing
Storage
Disposal
