Technical noteA selective process for extracting antimony
A complete technological process for extracting antimony from refractory gold ore was proposed. Antimony can be selectively removed from refractory gold ore by sodium sulfide leaching. Antimony was recovered in the form of sodium pyroantimonate It is essential to develop an economical and environmentally friendly process for the extraction of antimony from this ore.

Abstract. Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the In this study, a complete technological process for extracting antimony from refractory gold ore was proposed, which included leaching, pressure oxidation, A selective process for extracting antimony from refractory gold ore

Leaching Kinetics of Antimony from Refractory Gold Ore in
The ultrasound increases the extraction rate of copper from oxidized ore from 32% to 78%, shorts the reaction time and reduces energy consumption (Swamy and Narayana, 2001). The introduction of ultrasound greatly increased the leaching rate of Pb and Sb from lead-rich and antimony-rich oxidizing slag, or significantly shortened the Antimony mine areas refer to regions with favorable geological conditions for antimony ore extraction.

One-step extraction of antimony from low-grade stibnite in
The extraction of antimony from low-grade stibnite in eutectic Na 2 CO 3 –NaCl molten salt using ZnO as a sulphur-fixed agent was studied. The results of the experiments on the reaction mechanism indicate that the reaction courses of antimony and sulphur were Sb 2 S 3 →Sb 2 O 3 →Sb and Sb 2 S 3 →ZnS. Sulphur was fixed in the Tetrahedrite conventional leaching process is strongly chemical-dependent process which needs high temperature values for optimum extraction of antimony. However, this study revealed the fact that antimony dissolution from tetrahedrite by K 2 S and BaS is more economical and environmentally friendly than Na 2 S since mechanical agitation A Selective Method for Chemical Extraction of Antimony

Study on Pre-removal Antimony from Antimony–Gold
Antimony has a negative effect on the gold extraction from antimony–gold concentrate, and it is necessary to remove antimony in advance. For a high calcium low antimony–gold concentrate (Ca–Sb–Au ore), this study proposed to pre-remove antimony using slurry electrolysis in HCl–CaCl 2 system. The results indicated that the optimal This study aimed to introduce a vacuum process for recovering and enriching antimony from low-grade stibnite. At the pressure of 10 Pa, by controlling heating temperature, Sb 2 S 3 and Sb 2 O 3 from stibnite (12.8 wt% Sb) was evaporated and enriched. We investigated the influence of vacuum distillation temperature and time on Current processing technology for antimony-bearing ores a

Extracting antimony from high arsenic and gold-containing stibnite ore
The conventional extraction of antimony from stibnite and jamesonite involves a two-step pyrometallurgical process comprising volatilization roasting and carbothermal smelting (Ouyang et al., 2019; Tian et al., 2016). The sulfide antimony ore is first volatilized and oxidized into antimony trioxide (Sb 2 O 3) in a blast furnace, and then The complex As-Au-Sb ore is also an important antimony resource that is predominantly mined in Hunan and other places in China. It is essential to develop an economical and environmentally friendly process for the extraction of antimony from this ore.
