1. Introduction - Scientific Research Publishing

Stibnite ore of Kharan is a high grade ore and it contains 66% antimony sulfide as confirmed by X-ray diffraction (XRD) analysis. Therefore, up-gradation through froth-flotation is not required and instead of using concentrate the ore is employed directly for extraction of antimony metal as its recovery is better by iron precipitation since stibnite is a sulfide ore.
