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 name was derived from antimonite. In 1604, a process was invented to extract antimony and antimony sulfide as described by B. Valentine of Germany.

This paper demonstrates the possibility of expanding the antimony resource base in Russia by extracting and processing the multimetal gold-antimony ores of Kyuchus deposit in the Republic of Sakha (Yakutia), Russia. As a gold-bearing resource, Kyuchus ores are classified as refractory and difficult in terms of processing. This is due to the presence in the ore of arsenic, organic …
Antimony (Sb) is an impurity element that is increasingly encountered in the mineral processing/metallurgical industries of gold, copper and lead. Its occurrence in metallurgical feedstocks is in the form of various antimony minerals with stibnite, Sb 2 S 3, being the most important one. During processing antimony is mobilized reporting to ...
Heavy concentration of antimony processing in China ensures that a large share (14,000 MT, 79 percent) of U.S. antimony imports is sourced from Chinasimilar to other critical materials, like REEs and cobalt. 9 This reliance on China increases the potential for policy developments in to influence China antimony pricing. Developments in
Recently we reported a chemical doping approach to assist CIGS film grain growth using a hydrazine-based solution process [10], and demonstrated a significant grain size enhancement effect and subsequent solar cell device performance improvement at a given processing temperature, due to a small amount of antimony impurity incorporation in the ...
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.
The invention discloses a volatilization roasting process of antimony sulfide concentrate, which comprises the following steps: (1) mixing materials: carrying out ball milling and mixing on the antimony sulfide concentrate and the solid arsenic agent to obtain a mixture; (2) low-temperature high-oxygen potential arsenic fixation: spreading the mixture into a thin material layer, and …
A low-temperature and sulfur-fixing smelting process was applied to separate antimony from stibnite. The results show that the direct recovery rate of Sb is 90% (mass fraction), and the grade of ...
For the purpose of efficient and selective antimony recovery with minimal economic cost and environmental impact, researchers proposed various innovative …
There are two main types of modern antimony production methods—pyrometallurgy and hydrometallurgy [1,2,3].At present, the former is the main. The vast majority of antimony smelting enterprises have been using the traditional blast furnace volatile–reverberatory furnace reduction process, which is of low environmental protection, …
There are limited sources available on the antimony mines and processing facilities and their annual production. No public data was found on global antimony oxide production per country or facility. This study includes the production of the largest players in the supply chain, but greater transparency and better data reporting is highly ...
This paper demonstrates the possibility of expanding the antimony resource base in Russia by extracting and processing the multimetal gold-antimony ores of Kyuchus deposit in the Republic of Sakha ...
MOSFETs using antimony-doped source-drain (S/D) extensions. Also, the electrical characterization of shallow n/p junctions formed using antimony has been reported, 4,5 but these studies have not examined the electrical behavior in detail. In this paper,we present for the first time results of low-temperature processing of antimony-implanted
This paper focuses on the environmental leaching of antimony, a critical mineral, using deep eutectic solvents. Mining residues often contain embedded antimony, posing environmental risks. Deep eutectic solvents, known for being low in toxicity, cost-effective, and environmentally friendly, present a promising avenue for sustainable antimony extraction. The …

The existing studies on antimony focus on antimony supply and demand, trade structure and static substance flow analysis (Chu et al., 2019; Wang et al., 2021; Zhao et al., 2023b; Yu et al., 2021). To date, there is no study investigating the dynamic flows of antimony in China from a whole life cycle perspective, leading to that the key ...
4. The mineral processing of antimony Originally antimony was mined and hand sorted to effect con-centration. Since the bulk of primary production is in China, where labor is plentiful and cheap, surprisingly, hand sorting still finds a large application. However, in recent years, many other unit operations are used in the mineral processing ...
