China is the biggest antimony ore producer but production has declined to 40,000 tons in 2023 from 61,000 tons in 2020 as a result of falling ore grades and more stringent environmental requirements.
The antimony extraction by ozone in hydrochloric acid was employed and the influences of temperature, liquid/solid ratio, HCl concentration and stirring speed on the extraction of antimony were investigated. High antimony extraction (93.75%) is achieved under the optimized conditions.
Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its …
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 xide (Sb 2 O 3) in a blast furnace, and …
Tetrahedrite can be selectively dissolved by alkaline Na 2 S-NaOH lixiviant to extract antimony, arsenic, and even mercury while leaving copper and iron as …
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 …
Several extraction techniques and processing routes for gold recovery are available, depending on the types of gold ore and its mineralogical characteristics (Marsden and House, 2006;Natarajan ...

A complete technological process for extracting antimony from refractory gold ore was proposed. Antimony can be selectively removed from refractory gold ore by …
Moreover, sodium hydroxide can also extract antimony ore. The increase of the NaOH concentration is beneficial to the leaching of antimony. However, excessive alkali will causes the reaction between SiO 2 and NaOH to form dense Na 2 SiO 3. Na 2 SiO 3 will bind to the surface or pore of mineral crystals and prevent the leaching of …
Recognizing the imperative to address global climate change and promote sustainable development within the industry, the conventional antimony smelting process, characterized by high energy consumption and pollution, is confronted with escalating ecological and environmental pressures. This study proposes a two-stage method for …
However, it is often the primary focus of extraction in gold–antimony vein mining operations. The inclusion of antimony in gold ore poses challenges in terms of processing, leading to increased difficulty and cost. Consequently, it may be necessary to accumulate a quantity of gold ore with a significant antimony content [3,9].
ANTIMONY (Data in metric tons of antimony content unless otherwise noted) Domestic Production and Use: In 2019, no marketable antimony was mined in the United States. A mine in Nevada that had extracted about 800 tons of stibnite ore from 2013 through 2014 was placed on care-and-maintenance status in 2015 and had no reported production in …
Improved gold and silver extraction from a refractory antimony ore by pretreatment with alkaline sulphide leach. Hydrometallurgy (2011) ... Moreover, leaching this roasted gold ore resulted in gold extraction of 92.5%; however, leaching of refractory gold without pretreatment resulted in gold extraction of only 47.5%.

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 …
The saturated vapour pressure of antimony and its sulphide and oxide at different temperatures are shown in Fig. 2.As can be seen from Fig. 2, as the temperature increases, the saturated vapour pressure of Sb 2 S 3, Sb 2 O 3 and Sb increases gradually, and the growth trend of Sb 2 S 3 is the most rapid. When the temperature is below 1201 …
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 …
Antimony price, history, occurrence, extraction and use. antimony. Antimony (from Latin Antimonium, probably from Arabic "al-ithmîd (un)" is a chemical element with the element symbol Sb (from Latin Stibium, (gray) pike gloss) and the atomic number 51 In the periodic table it is in the 5. ... Antimony (or a preparation derived from antimony ...
Hydrocarbons with a high thiol content significantly enhance the extraction of antimony metal from ore-forming wall rocks. Consequently, in sediment-hosted antimony deposits, organic fluids, rather than aqueous fluids, primarily facilitate antimony transfer. The hydrocarbons found in the inclusions are likely the remaining organic …
To avoid the adverse effects of antimony on the cyanide leaching process used for the recovery of gold from refractory gold ore, a cleaner production process was proposed that would selectively remove antimony as sodium pyroantimonate. The process included three steps: 1) leaching of antimony from the refractory gold ore with sodium …
In this work, a two-step vacuum metallurgy method was proposed to produce Sb2S3 from complex lead-antimony sulfide ore. As revealed from the experimental results, jamesonite (Pb4FeSb6S14) is overall decomposed into PbS, Sb2S3 and FeS at 750 °C. The first step vacuum distillation was performed at 650 °C for 80 min, by which the purity of Sb2S3 …
