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.
The definition of lowgrade depends on the resource in question. For copper, low grade ores have less than 1% copper. For gold, an ore having 1% gold by mass would be considered (very) highgrade, as gold is more valuable than copper.
