In this work we consider stibnite mineral with chemical composition Sb 2 S 3 as a candidate. Stibnite is the predominant ore mineral of antimony, distributed over the earth's crust at 0.2–0.5 ppm (ppm) .Global production of antimony …

 · Vegilo et al.16 have previously used response surface methodology (RSM) for designing experiments, and as a modeling and optimizing tool, to determine the optimal condition for the dissolution of Sb. Their results indicated that using 1 g Na 2 S and 1 g NaOH per g of pure stibnite can provide an antimony leaching efficiency up to 98–. …

Stibnite is named after the latin stibium, which is the old name of the element antimony (Sb). Stibnite was and continues to be the primary ore of antimony. Stibnite forms some of the most outstanding natural crystals that exist, in way of sharpness, luster, and size.It can form in groups of huge metallic lustered crystals that are elegantly crafted and exceptionally …

stibnite, antimony sulfide (Sb2S3), the principal ore of antimony. This mineral has a brilliant metallic lustre, is lead- to steel-gray in colour, and fuses readily in a candle flame (at about 525° C [977° F]). It often possesses a bladed habit, is striated, and has one perfect cleavage. Stibnite occurs in massive forms in gneiss and granite.

 · The main purpose of this study is to characterize and separate antimony from a stibnite concentrate through a low-temperature sulfur-fixing smelting process.
