Antimony (Sb), a toxic metalloid element, is located in the Group VA of the fifth period of the periodic table of elements. At present, with the wide use of antimony containing products in the world and the corresponding mining activities, a large number of antimony containing waste generated in these processes has also been released to the …
Antimony is a 'critical metal' in short supply in the world markets (Gunn 2014). Mining of antimony ores in Myanmar reached 9000 metric tons in 2014 (USGS 2015), establishing Myanmar as a significant global source of antimony ore, the bulk of which is exported to China. The majority of the antimony ore in Myanmar is in syntectonic quartz–stibnite …

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 smelting. The performance of most of the pyro-processes is very sensitive to concentrate type and grade. Therefore, technology …

Although China has the largest antimony reserve in the world, the over exploitation has led to the depletion of such antimony resource. According to the static reserve-production ratio adopted by the United Sates Geological Survey (USGS), the mining life of antimony ore is lower in China (4.9 years) than the global average (11 …
The Tha Byu Mine is currently the largest producer of antimony ore in Myanmar. Antimony ores have been mined at the Tha Byu Mine since the early 1920s and, prior to 1948, production totalled over 5200 tonnes of ore @ 50% Sb. Subsequently the mine was dormant, although artisanal mining took place during the 1980s.
The high criticality of antimony was illustrated in 2021, when the price of Chinese antimony reached a seven year high, caused by a shortage in ore supplies …
A hydrometallurgical process based on leaching with chloration, hydrolysis, neutralization with ammonia water, is developed for preparing antimony white powders from the multi-metal Sb-Pb...
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 …
process a major portion of the world's antimony, China's downward trend in mining antimony production has not affected its rank as a top antimony producer. This is also due to China sourcing from other producers that have recently substantially increased antimony mining, such as Russia (30,000 MT of production in 2020), Tajikistan
Download reference work entry PDF. ... Since 1930, antimony ore melting in blast furnace became an important process for producing antimony metal. In China, antimony ore was discovered at a tin mine in Hunan during the Ming Dynasty (1368–1644). In 1908, Huachang Company of Hunan imported the volatilization roasting …
Antimony (Sb) is a naturally occurring metalloid capable of forming toxic products, is a suspected carcinogen (Gebel 1997; ATSDR 2019) and has been classed as a priority substance (ATSDR, 2017).Antimony can be enriched in soils as a result of the mobilization of antimony from minerals and waste antimony ore and activities including …
