Stibnite is a chief ore of antimony, which is a crucial mineral with industrial and medical uses. It is a sulfate mineral often found in hydrothermal veins. In the initial stages, stibnite is lustrous gray, black, and silver, and when fully formed, it exhibits an iridescent quality that is muchly prized and collected.
Scheelite and stibnite are prevalent ore minerals in Sb-W deposits, making their trace element compositions valuable for enhancing our understanding of the genesis of Sb-W ore systems. In this study, we conducted a systematic investigation of trace element compositions in scheelite and stibnite samples from the Chashan and Zhazixi Sb-W …
The electrochemical properties of the Sb 2 S 3 /SCS composites and stibnite ore were studied as SIBs anode by cyclic voltammetry in the voltage range of 0.01–2.5 V. As depicted in Fig. 5a, the first cathodic scan exhibited two current peaks located at 0.67 V and 0.26 V, which were ascribed to the conversion reaction with the sulfur atoms in material …

Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from …
The rate of oxidation of stibnite is strongly dependent on pH with appreciable dissolution at pH 10 reducing to low levels at pH 12. Fig. 1 shows Hedley and Tabachnick's (1958) results of the cyanidation of a synthetic ore containing 0.25% stibnite at pH values of 10, 11 and 12.. Download : Download full-size image Fig. 1.

The trace element composition of hydrothermal ore minerals generally depends on the following characteristics of ore-forming fluids: redox state, pressure, temperature, pH value, and fluid source regions; these, have been used widely to illustrate ore genesis for various hydrothermal deposits (Wang et al. 2020a; Li et al. 2020a, …
In addition to recovering Sb from the primary ore i.e. stibnite, the secondary resources of Sb should also be explored. End-of-life products or electronic wastes can …
During the SE, stibnite disappeared, leaving behind elemental sulfur. We proposed a comprehensive procedure for the separation and recovery of antimony from the As-Au-Sb ore.

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 …
