Treatment methodologies needed for antimony effluents from antimony mining and smelting industries are different from antimony decontamination in nuclear reactors. The problem of antimony leaching from a polyethylene terephthalate bottle is very much different from the leaching of antimony from mining wastes.

The rapid development of the smelting industry increases the release of antimony (Sb) into the soil environment, which threatens human health and ecosystems. A total of 87 samples were collected from an abandoned Sb smelting site to evaluate pollution characteristics and environmental risks of the potentially toxic elements (PTEs).
It was demonstrated that contaminated soil profiles showed distinct depth-resolved effects when compared to uncontaminated soil profiles, and metagenomic results indicated that microbial metabolic potential also changed with soil depth. Antimony mining has resulted in considerable pollution to the soil environment. Although studies on antinomy …
Antimony mining has resulted in considerable pollution to the soil environment. Although studies on antinomy contamination have been conducted, its effects on vertical soil profiles and depth-resolved microbial communities remain unknown.
The powdery crude antimony xide is reduced by a carbonaceous reductant in a reverberatory furnace at 1,000–1,200 °C to produce crude antimony. Crude antimony can be produced by the precipitation smelting process. The typical pyrometallurgical antimony production process using sulfide ore is shown in Fig. 1.
The main method of pyrometallurgy is the volatilization smelting in blast furnace of antimony concentrate. During the smelting process of antimony concentrate, a large amount of smelting slag is produced, including smelting slag, arsenic alkali slag, lead removal slag, and so on.
Antimonial dust is a by-product of lead smelting and an important material for extracting antimony. A new pyrometallurgical process for producing antimony white from the antimonial dust is reported. The process mainly consists of three steps, which are reduction smelting, alkaline refining, and blowing oxidation. First, the reduction …
The slag dumped from oxygen-enriched smelting of a bottom-blown furnace or antimony smelting of a blast furnace is a valuable source of antimony, but without treatment, it may cause enormous waste of resources and constitute an ecological threat to the surrounding environment.

The distribution, bioavailability, and accumulation of antimony (Sb) at the interface of rhizospheric soils and indigenous plants from a large Sb mining/smelting area in Southwest China were explored. Results showed that the local soil was severely polluted by Sb, and the aluminum magnesium silicate …
At that time Cookson (under the name Anzon, Limited) produced antimony and zircon in Europe. The Laredo operation became Anzon American and later Anzon, Incorporated. Among the company's products is an antimony oxide known as TMS (from Texas Mining and Smelting Company).
The dissimilatory Fe(III)-reducing bacteria play a significant role in the mobility of antimony (Sb) under reducing environment. Sb-rich smelting slag is iron (Fe)-containing antimonic mine waste, which is one of the main sources of antimony pollution.
A new pyrometallurgical process for producing antimony white from antimonial dust was proposed, and it has many advantages such as shorter process, lower cost …
The antimony and gold content obtained in the electric furnace melting process is lower compared with blast furnace smelting process, indicating that gold content in the antimony matte is strongly dependent of antimony content.
Antimony smelting activities damage the soil and vegetation surroundings while generating economic value. However, no standardized methods are available to diagnose the extent of soil degradation at antimony smelting sites. This study developed a standardized framework for assessing soil quality by considering microbial-induced …
AbstractCleaning of high antimony smelting slag from an oxygen-enriched bottom-blown was tested by direct reduction in a laboratory-scale electric furnace. The effects of added CaO, mass ratio of coal (experimental) to coal (theoretical) (ω) and the slag type on the reduction procedure were considered. The contents of Sb and Au were …

The traditional method of producing antimony metal is through heat smelting. However, researchers at MIT claim to have accidentally stumbled upon a new method of smelting using electrolysis rather than heat.
The removal of antimony from antimony dust captured during the direct lead smelting process has been studied by Liu et al. They proposed a pyrometallurgical …

A large amount of solid waste has been produced by the antimony smelting process in the "World Capital of Antimony", Xikuangshan area in China. This study comprehensively investigated the physical and chemical characteristics of the various solid wastes, as well as the leaching behavior of the solid wastes, which included water …
Keywords Antimony mine area Antimony pollution Phytoavailability Soil Speciation Introduction Antimony (Sb) is a toxic element that is found throughout the environment. This trace element has an estimated average abundance of 0.2 mg kg–1 in the earth's crust (Smith and Huyck 1999) and background concentrations in soils of
The phase transformation mechanism of antimony sulfide in the oxygen-enriched smelting system was investigated. The standard Gibbs free energy change (ΔGθ) of reactions in the smelting system at 100 ~ 1400°C were calculated, indicating that the reaction between Sb2S3 and oxygen was liable to occur first, and that the high-valent …
