Antimony has a range of industrial uses in batteries, chemicals, ceramics and glass but by far the most important is in fire retardants. The economically most important ore mineral and principal source for the production of antimony is stibnite. Majority of antimony-bearing ore deposits are associated with the subduction-related western …
Antimony mainly occurs as stibnite (Sb 2 S 3) in a variety of intermediate-low temperature hydrothermal ore deposits worldwide and has been the simplest matrix to analyze. Scant Sb isotopic data from stibnite exists in the literature described above, yet the key controls of its isotope fractionation in these systems are still largely unknown.
Moreover, China's antimony ore mining accounted for 52% of the world's antimony mining in 2020, with extraction of antimony ores also ranking first in the world . With the increasing development of mining technology, the production process of antimony mineral resources, mainly jamesonite and stibnite, has become increasingly mature.
6.1 Antimony (Stibnite Ore) Antimony deposits and prospects in the form of quartz- stibnite veins and replacement bodies are scattered in the Slate belt between Papun and 15°N. Clegg gives a summary description, based on Heron in Clegg (1944a), of the deposit at Thabyu village (15°35′N, 98°07′E), 70 km southwest of Thanbyuzayat.
If antimony ore contains more than 90% stibnite, it can be sold directly for producing antimony compounds or conversion to antimony metal (Herbst . et al., 1985). Crude materials marketed for the manufacturing of pure antimony products (mostly oxide) consist of antimony sulfide concentrate and lump antimony sulfide ore (USGS, 2001). 4
Table 1. Fractionation experiment outline. Stibnite "China 3" was selected. The crushed ore was heated at 400°C in order to obtain Sb 2 O 3. Then the roasted stibnite was heated with C at 500°C during 4 h. This was …
ANTIMONY (Data in metric tons of contained antimony unless otherwise noted) Domestic Production and Use: In 2021, 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 …

Project objectives are to document the origin of the Yellow Pine gold-antimony deposit and, by extension, the origin of this deposit type. Our goal is to understand the structural, tectonic, and magmatic setting of the deposit, the character of the ore-transporting fluids, the conditions of ore deposition, and the regional stratigraphic …
Antimony compounds are used in medicines, the rubber and patent-leather industries, paint pigments, enamelware glazes, and as fire-proof coatings on clothing. Mining of antimony ore has been limited to northern Sevier County, although some stibnite is also present in Pike County, associated with cinnabar (HgS).
The quantity of antimony in a sample can be determined by an oxidation–reduction titration with an oxidizing agent. A 5.77 g5.77 g sample of stibnite, an ore of antimony, is dissolved in hot, concentrated HCl(aq)HCl(aq) and passed over a reducing agent so that all the antimony is in the form Sb3+(aq).Sb3+(aq).
Monday, January 5, 2015 David Guberman, the antimony commodity specialist for the National Minerals Information Center at the U.S. Geological Survey, compiled the …
Bismuthinite-Stibnite Series. Possibly also polymorphous with UM1996-35-S:Sb. The most common antimony sulphide. An important Sb ore mineral. ... Diemar, Glen A., Filella, Montserrat, Leverett, Peter, Williams, Peter A. (2009) Dispersion of …
Antimony. Stibnite from Comadai near Bacchus Marsh, Victoria (Scale: 5 cm) When used as an alloying element, antimony greatly increases the hardness and mechanical strength of lead. The main use of antimony is to harden lead in storage batteries, and it is increasingly being used in the semiconductor industry.
Stibnite, the most common antimony mineral, occurs in veins hosted in carbonate rocks such as limestone. Nearly pure stibnite may occur in lenses tens of meters long, making for very rich ore. Gold-antimony epithermal deposits are the second most common type and contain 20 percent of the world's antimony. In these deposits, ore occurs in ...
In our previous study, the leaching and electrowinning of antimony from a high arsenic and gold-containing stibnite concentrate ore using SE process in a medium of HCl–NaCl was investigated Zhang et al. . The antimony was selectively leached, while gold and arsenic were retained in the residue as a raw material for further gold extraction.
Stibnite, jamesonite, and antimony-gold ores are the most common sources of antimony. The two formers are typically found with lead ores in nature . Antimony-gold ores mostly consist of gold and antimony sulfide intergrowth and aurostibite (AuSb 2) . Russia, Bolivia, Australia, and China have gold-antimony ore deposits . Copper-rich …
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 …
Stibnite is the principal ore of antimony. The mineral is widely admired for its spectacular crystalline habits, which exhibit extremes of sharpness, luster and size. Its principal metallic component, …
The quantity of antimony in a sample can be determined by an oxidation–reduction titration with an oxidizing agent. A 7.69 g7.69 g sample of stibnite, an ore of antimony, is dissolved in hot, concentrated HCl(aq)HCl(aq) and passed over a reducing agent so that all the antimony is in the form Sb3+(aq).Sb3+(aq).
The use of antimony continued in the Iron Age. The Urartian cemetery in Yoncatepe Kalesi in Van (Turkey) yielded antimony buttons made from sulphur-bearing antimony ore, such as stibnite [76: p.188, fig. 9]. Similar antimony and antimony–lead alloy buttons were documented as burial goods from Middle and Late Iron Age Armenia
The most common antimony ore mineral is stibnite (Sb2 S3 ), but more than 100 other minerals also contain antimony. The presence of antimony in surface waters and groundwaters results primarily from rock weathering, soil runoff, and anthropogenic sources. Global emissions of antimony to the atmosphere average 6,100 …
The antimony content in the cathode antimony was >98%, and arsenic content was less than or equal to 0.21%. The As-Au-Sb ore consisted of stibnite (Sb 2 S 3), pyrite (FeS 2), arsenopyrite (FeAsS), and quartz (SiO 2), along with a small amount of muscovite (KAl 2 (AlSi 3 O 10)(OH) 2) and other gangue phases. Antimony mainly …
In Carlin-type gold and antimony deposits of the basin, the δ 34 S values of ore pyrite are higher than those of stibnite (Hu et al. 2002; Chen et. 2018; Yan et al. 2018). This is consistent with that 34 S enrichment follows the general trend SO 2− 4 > SO 2− 3 > SO o x > SO 2− (Bachinski 1969; Seal 2006 ), and indicates that the isotopic ...
The exploitation of this stibnite ore deposit, including mining, ore processing, and metallurgical activities, generated large volumes of waste. Mine waste rocks were accumulated in dumps, whereas mine tailings and smelting waste were deposited separately on the land. ... Dispersion of antimony from oxidizing ore deposits. Pure Appl. Chem., 81 ...
