Antimony gravity separation processing machines primarily refer to the stibnite jig machines while sometimes it is shaking tables. Floatation separation is also kind of an important beneficiation method for stibnite antimony ore. Flotation techniques can be used to upgrade antimony sulfide minerals further after gravity separation.

Jul 15, 2006· The article describes the properties, production, and usage of the element antimony and its primary compounds. Stibnite, which is referred to as crude antimony when its Sb 2 S 3 content is above 90 %, has a low melting point and it can be extracted by melting (liquidation). Antimony metal is recovered from ore primarily by pyrometallurgical techniques.

The ore bodies mainly occur in lamellar, quasi-lamellar and lenticular forms in the altered rocks, and are strictly controlled by anticline structure.
