For the comprehensive utilization of antimony smelting arsenic-alkali residue, there are some problems such as the incomplete separation and low recoveries of arsenic and alkali, and the formation of arsenic-alkali mixed salts with secondary pollution.
Water samples from Xikuangshan (China), the world largest antimony (Sb) mine with a Sb mining and smelting history of more than 200 years, were analyzed. These water samples ranged from stream water in the vicinity of the mining and smelting area that received seepage from ore residues to the underground mine-pit drainage. The …
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 …
This study demonstrates an efficient and clean process for the purification of crude As 2 O 3 recovered from antimony smelting arsenic-alkali residue, which has potential application for purifying crude As 2 O 3 recovered from arsenic-containing wastes. Declaration of Competing Interest.
Arsenic and antimony are separated during the copper smelting, laying the foundation for the subsequent recovery of arsenic from dust and antimony from slag, respectively. Many researchers have studied the multi- phase distribution behavior of antimony in copper smelting.
Background Soil microbes play critical roles in the biogeochemical cycling of antimony (Sb) and arsenic (As), and the effects of Sb and As contamination on soil microbiota have been well ...
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 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.
Antimony pollution in water bodies happens through runoff water from the natural weathering of antimony ores or minerals, soils that are contaminated with dust …
Water samples from Xikuangshan (China), the world largest antimony (Sb) mine with a Sb mining and smelting history of more than 200 years, were analyzed. These water samples ranged from stream water in the vicinity of the mining and smelting area that received seepage from ore residues to the underg …
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 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.

The controlling factors of antimony migration and transformation in soil profiles are still unclear. Antimony isotopes might be a useful tool to trace it. In this paper, antimony isotopic compositions of plant and smelter-derived samples, and two soil profiles were measured for the first time. The δ …
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 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 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 … Expand
The antimony smelter was founded in 1986 and ceased production in 2013, mainly engaged in antimony smelting. The antimony reserves of the antimony mine belonging to the antimony smelter ranked third in China and first in the Northwest. The company's main product was refined antimony, with an annual output of 3000 tons.

The antimony smelting techniques that have been developed in Xikuangshan are typical of smelters in China. Traditional smelting methods have been improved since the 1940s, …
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 …

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 …
The results show that the distribution of arsenic, antimony and bismuth in different smelting processes is quite different. Arsenic, antimony and bismuth in copper concentrates are mainly converted to by-products such as dust, slag, anode slime and black copper after smelting, blowing and electrolytic refining.
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.
