1. Introduction Scientific Research Publishing

Stibnite ore of Kharan is a high grade ore and it contains 66% antimony sulfide as confirmed by Xray diffraction (XRD) analysis. Therefore, upgradation through frothflotation 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.

Metal Extraction Process for High Grade Stibnite of Kharan

A rapid and simple process has been developed for the recovery of antimony metal from stibnite ore of Kharan area (Balochistan) of Pakistan. The ore was characterized by Xray diffraction (XRD) technique and found to contain 66% stibnite i.e. antimony sulfide (Sb2S3). The process parameters for the extraction of antimony were optimized on laboratory scale by varying reaction temperature from
