Heavy metal pollution of soil caused by mining and smelting activities has become a major threat to land use (Karczewska et al. 2004).Contamination of antimony (Sb) and arsenic (As) in soil is an important environmental problem worldwide (Filella et al. 2002; Wilson et al. 2010).Sb is a suspected carcinogen with potential damage to the …

Technical Products and Impurities: Antimony (III) sulfide, 68.5% Sb, 27% sulfur, as a black powder, is available from Sigma-Aldrich (2001a,b). 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

In this study, we demonstrated the role of the Cambrian strata in supplying sulfur and ore-related elements by in-situ sulfur isotope and trace element analyses on …

Antimony. A native element, antimony metal is extracted primarily from stibnite, which contains 72 percent antimony and 28 percent sulfur. Stibnite is mined in only a few countries, with China being its largest producer. Antimony is used for many technological and industrial purposes. Antimony is used as a hardening alloy for lead, especially ...

The antimony ore beneficiation methods mainly include manual separation, gravity separation, flotation, and other methods. Select the beneficiation process of a specific ore based on the physical and chemical properties of the ore type (natural type and industrial type), mineral composition, structural structure, and process particle size of useful minerals.

Antimony metal and various antimony compounds (such as antimony trioxide and trisulphate) are produced from the ore. Exposure to antimony dust occurs during the mining, crushing and processing of the ore; however the highest exposures to both antimony dust and fumes are likely to occur in smelting and refining processes. ...

The occurrence of antimony (Sb 0) in its original state is rare, mostly because of its high affinity for sulfur and other metals/metalloids, including cobalt, lead, …

Environmental context Phytoremediation requires an understanding of bioconcentration and translocation processes that determine behaviour and fate of potentially toxic elements. We studied the distribution of antimony and arsenic in terrestrial and aquatic soil-plant systems in an antimony ore zone. We found that the common …

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 …

Only about ten of them have any of antimony has been used for antimony batteries in industrial value, usually those including stibnite, both the military and automotive industries; this has jamesonite, senarmontite, yellow antimony ore, sulfur led to a sharp increase in the demand for antimony [5].

The most common antimony ore mineral is stibnite, which may contain traces of other metals, including copper, iron, gold, lead, and silver (Pohl, 2011). Stibnite occurs in numerous mineral deposit types (Cox and Singer, 1986). Antimony ore may also carry undesirable elements, such as arsenic and mercury (Pohl, 2011).

Antimony is seldom found in nature as a native metal because of its strong affinity for sulfur and metals such as copper, lead and silver. In fact, the word antimony ... In ancient times, in extracting antimony from sulfide ore by the addition of iron, a starlike fern shaped crystalline pattern appeared during the course of solidification. ...

The Leishan-Rongjiang antimony ore field (LAOF) is in a unique geotectonic location in the uplift between the Youjiang and Xiangzhong basins. This paper focuses on two representative deposits in ...

Sulfur in crude antimony is present in the form of Sb 2 S 3. Since the chemical properties of antimony and sulfur are largely different, it can be easily removed. This is rather evident from the Sb-S phase equilibria where liquid antimony and molten Sb 2 S 3 are immiscible. That is, only up to 1.5 wt% sulfur dissolves in antimony.

The identification of metal and sulfur sources in hydrothermal Sb ore deposits has long been recognized as a challenging task. Stibnite is commonly found as one of the primary ore minerals in most antimony deposits, and it can even occur as the sole ore mineral in some large antimony deposits; therefore, the sulfur isotope …

Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.

The Mineral antimony. Antimony is a native element that can occur in a natural state, but it is rarely pure. It almost always contains some arsenic, and may also contain traces of silver, iron, and sulfur. On a fresh or preserved surface, Antimony has a tin-white color with a slight blue tinge. Otherwise, it is dark gray due to tarnish.

The sulfur isotope test reveals that the δ 34 S values of gold and antimony deposits both concentrate in a small range near 0‰, and the S isotope composition is similar to that of mantle sulfur, indicating that the sulfur in the ore-forming materials of the gold and antimony deposits mainly come from deep mantle. The research results lay the …

Antimony (Sb) is a chemical element of the periodic table, located in the group 15 and the period 5, and is having the atomic number 51. It is a hard, brittle, lustrous, silvery-grey metalloid, whose name comes from the Greek word "anti-monos", which means not alone. It is a member of the pnictogen group.

Abstract. The supergiant Xikuangshan Sb deposit is located in the Middle to Upper Devonian limestone of central Hunan, China. Primary ores are composed of early‐stage stibnite and calcite with rare pyrite, early main‐stage stibnite and quartz, and late main‐stage stibnite and calcite. New sulfur isotope data reveal the clustering of δ34S …

Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction …

The clean production process for extracting antimony from refractory gold ore involves sodium sulfide leaching, pressure oxidation, concentration, and crystallization steps. First, the stibnite in the refractory gold ore reacts with sodium sulfide, and antimony is dissolved into the leaching solution in the form of sodium thioantimonite …

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 has a strong affinity with sulfur; thereby, it is classified as a chalcophile element. Moreover, it is often seen to create chemical compounds with a range of metallic

Evidence for the occurrence of antimony can be traced back to antiquity. 1 The name comes from the Greek, anti and monos, meaning 'metal not found alone'. 2 Indeed, antimony is usually found as the sulfide ore, stibnite, Sb 2 S 3, the black form of which was used by ancient Egyptian women as a cosmetic for darkening their eyebrows …
