Stibnite - an overview ScienceDirect Topics

Stibnite or antimonite is sulfide metalloid mineral of antimony with chemical formula (Sb2 S 3 ). The color is shiny lead-gray tarnishing to black with massive, granular, radiating, and elongated crystals habits ( Fig. 1.50 ). The mineral contains 71.7% antimony in its natural purest form. Stibnite crystallizes in orthorhombic system, needle ...

Stibnite froth flotation: A critical review - ScienceDirect

2021-3-15  Several other authors have also studied the floatability behaviour of stibnite as a function of pH at the microscale by introducing a series of variations in their tests: ore type (Derjaguin and Shukakidse, 1961), addition of reagents (frother, collector, activator, depressant) (Kaigua and Dianzua, 1985, Popov et al., 1987, Richards, 1977), or flotation time (Laskowski,

2021-5-28  or high concentrations. After the ore is mined and crushed, it will be placed in large tanks and mixed with a dilute sodium cyanide solution that contains less than one percent cyanide. This process extracts the gold from the ore and allows us to recover it to make mixed gold-silver doré bars for further processing off-site.

Optimisation of Pure Stibnite Leaching Conditions by ...

2015-12-27  Chemical leaching of pure stibnite has been studied in order to optimise the concentration of the used reagents in the basic leaching (Ubaldini et al., 2000b). A centred 23 full factorial design has been planned in order to evaluate the effect of Na2S, NaOH and ore concentrations on the Sb extraction yield.

Metal Extraction Process for High Grade Stibnite of

2017-1-12  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 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
