The only major antimony deposit in North America is located in the Stibnite-Yellow Pine Mining District of central Idaho. This site is the largest reserve in the nation and is expected to supply roughly 35% of U.S. antimony demand on average for the first six years of production.
The mineral processing of antimony. Originally antimony was mined and hand sorted to effect concentration. 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 …

Zhang et al. [54] studied the recovery of antimony and bismuth from pres-sure-leached flue dust created during the smelting of cop-per. They used a three-step process consisting of a kerosene desulfurization step, a chloride leaching step, and a final hydrolysis step to recover 95.80 % of Bi and 90.8 % of Sb.
The pollution of heavy metals and their harm to human health and the ecological environment have caused widespread concern. In this research, we collected Qinglong antimony mine tailings (8-meter deep) and then analyzed the content changes, geochemical behavior, and ecological risk assessment of 7 heavy metals (Sb, As, Cr, …
Antimony is an important mineral commodity used widely in modern industrialized societies. The element imparts strength, hardness, and corrosion resistance to alloys that are used in many areas of industry, including in lead-acid storage batteries. Antimony's leading use is as a fire retardant in safety equipment and in …
Unfortunately, no large-scaled and easy-to-mine antimony deposits were found in China recently. Therefore, it is urgent to seek more supply channels so that the increasing demand for antimony can be met with ... Current processing technology for antimony-bearing ores a review, part 2. Miner. Eng., 2 (4) (1989), pp. 543-556, …
open access. Highlights. •. The antimony diversity of supply of both mining and refining is low. •. Almost 70% of Sb is mined as by- or co-product. •. Companion …
Abstract. Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Anti …
The results are presented for using microorganisms for mercury and antimony separation and extraction of oxidized antimony minerals. The problems on technology of direct processing of gold-antimony concentrates by pentachlorous antimony chlorides are considered. The perspective is shown for leaching antimony by alkaline solution of …
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 …
The Project is one of the highest-grade, open pit gold deposits in the United States and is designed to apply a modern, responsible mining approach to restore an abandoned mine site and produce ...
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 …
Antimony (Sb) is an impurity element that is increasingly encountered in the mineral processing/metallurgical industries of gold, copper and lead. Its occurrence in …
US Antimony, which received a $510,500 grant from the US Department of Defense, has the only primary antimony processing facilities in North America and the Stibnite Gold project is poised to...
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. Research was funded by the US Department of Energy, the Advanced Research … See more
1. Introduction. With the development of antimony mines and the expansion and development of their mining areas, the health of antimony mining villages' inhabitants is deteriorating (Jiang et al., 2020), and the pollution of toxic elements in the rural topsoil and its environmental safety have attracted widespread attention.In addition, Sb and its …

Mining and processing capacity should be developed simultaneously, because processing is also concentrated in China. Together with the development of new primary sources, secondary sources could also provide significant amounts of antimony. ... Heavy metal pollution of the world largest antimony mine-affected agricultural soils in …
The article presents results of hydrometallurgical and bio-treatment of antimony ores and recommend new dissolvents for antimony sulfides.

Antimony Metallurgy. 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. …
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 ...
Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production.
