Antimony mining areas generate a large amount of wastewater containing complex heavy metals, which poses a threat to the health of residents and surrounding flora and fauna, and disrupts the ecological balance. Therefore, it is necessary to find more effective means of treatment. By reviewing the formation, risks, and treatment methods of …
There is currently no domestic antimony source, and 90% of world supply is controlled by China, Russia and Tajikistan, a narrative becoming increasingly untenable when it comes to sourcing minerals crucial to North America's supply chain. "[Antimony] deserves much more credit than it gets – ultimately it's the uns…See more on mining

The International Antimony Association, or i2a for short, is the Brussels-based organisation that represents the producers, importers and users of Antimony. Our aim is a sustainable and responsible Antimony industry being achieved through product stewardship ensuring safe use and responsible management of Sb substances. More About i2a.
Elevated soil concentrations of antimony (Sb) and co-contaminants are frequently encountered where antimony has been mined on a large scale. For instance, the Xikuangshan antimony mine in central South China has sustained, over many centuries, dispersed and spatially variable input of toxic elements into the soil ecosystem. We …
Based on a long-term antimony price of $8,500 a ton, the company estimates that the net present value of the project is around $279m. Future outlook. Although mining antimony is cheaper in China because of labour costs and the typically large deposits, the trend in declining production is set to endure.
The Project is designed to restore environmental conditions in the historical Stibnite mining district while responsibly developing one of the highest-grade open pit gold resources in the United States and becoming the only domestically mined source of the critical mineral antimony. Mining activity first started in the district in the early ...

World antimony production peaked at 203,500t Sb in 2011, driven by continued growth in consumption in flame retardants and lead-acid batteries, according to a new study by Roskill.
This work aims to establish Sb mobility, its transfer to biota and its effect on soil health in a semi-arid climate. The results show the presence of stibnite (Sb 2 S 3) as the main primary Sb compound, bindhemite (Pb 2 Sb 2 O 6 (O,OH)), and minor proportions of stibiconite (Sb 3+ (Sb 5+) 2 O 6 (OH)) as oxidised Sb species. This research also …
Antimony is a silverly, lustrous grey metal that exhibits poor heat and electrical conductivity. It is relatively soft, measuring only 3.25 on Moh's scale of mineral hardness. Known as "stibium" in classical Latin, antimony is represented by the chemical symbol Sb. A member of the arsenic group of elements, antimony is commonly found in ...
Antimony is one of 35 federally designated critical minerals for its use in the national defense, technology and green energy sectors. It has also been named a critical …

This study investigated soil microbial community in a typical gathering area of antimony mining and smelting in South China. The physical and chemical properties of different soils (mining waste dumps, flotation tailings, and smelting slag) and depths (0–20 cm, 40–60 cm, and 80–100 cm) were compared. The results showed that antimony (Sb) …
Antimony naturally occurs in the Earth's crust. More importantly it's used in screens, batteries and to make heat sensitive products flame retardant.
Alaska has stepped up to meet America's strategic antimony needs in the past and hosts rich deposits of the heat resisting metal that could help fill current and future critical needs. Lifesaving heat resistance. From children's playrooms to army tents, antimony's resistance to heat has saved countless lives.
Relation to Mining. Antimony rarely occurs in its native metallic form in nature. It easily combines with other elements, usually including sulfur, to form over 100 different minerals. Of these minerals, only stibnite (Sb2S3) is mined commercially as a source for metallic antimony. Antimony is found in trace amounts in silver, copper and lead ...
