antimony production from stibnite

Clean antimony production from stibnite concentrate with ...

2021-9-1  Antimony can be extracted from stibnite as crude antimony bullion by co-treating with a goethite residue without Na 2 CO 3 addition (Li et al., 2020). At the same time, sulfur in stibnite and iron as well as zinc contained in the goethite residue could be conserved as sulfides, naturally separated and layered from the slag and recycled as a ...

US3944653A - Process for preparing high purity antimony ...

Antimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable by-products. The high purity antimony trichloride may be hydrolyzed to form high purity antimony oxide.
