SULFIDE ORES: The mineral dressing of sulfide ores is primarily accomplished by flotation although it can be accomplished by gravity and hand sort methods. Recoveries of unoxidized sulfides can be in the mid 90% range with concentrate grades of 60 to 68% for stibnite ores. The stibnite concentrates are then fumed to a crude oxide that is either fumed to a finished oxide or reduced to metal ...

Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb2S3. This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek στίβι stibi through the Latin stibium as the old name for the mineral and the element antimony.
