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 sulfate-reducing bacteria. The …
low levels of Sb in the ore:< 50 mg/kg in bulk ore, and up to 2000 mg/kg in solid solution in arsenopyrite (Craw and MacKenzie 2016). However, additional Sb-bearing sulde concentrate (≈ 4000 mg/kg Sb) was transported for nine years from the Reefton mine (Fig. 1a, c; Milham and Craw 2009) to the Macraes mine for processing in the Macraes

The primary sources of antimony extraction are stibnite (antimony trisulfide) and valentinite (antimony xide). The extraction process typically involves several steps, including mining, concentration, and smelting. Mining involves the extraction of antimony-rich ore from underground or open pit mines.
A hydrometallurgical process based on leaching with chloration, hydrolysis, neutralization with ammonia water, is developed for preparing antimony white powders from …

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 veins and breccias (Type I of Dill …
The norank_c_Acidobacteria is one of the top five genera found in gold mining areas [56]. In the typical antimony ore smelting area in the south of China, at the genus level, the bioindicators ...
Antimony can be enriched in soils as a result of the mobilization of antimony from minerals and waste antimony ore and activities including mining, mineral smelting and the use of drugs and pesticides (Okkenhaug et al. 2016; Wang et al. 2011), allowing interaction with the wider hydrological, biological and surface environment (Filella et al ...
The Stibnite-Yellow Pine mining area in central Idaho hosts gold, antimony, and tungsten in metasedimentary strata and Idaho batholith rocks. Garnet Lu-Hf geochronology and geothermobarometry ...
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 mining, mineral …
In recent years, international research on the toxicity of the heavy metal, antimony, has gradually changed focus from early medical and pharmacological toxicology to environmental toxicology and ecotoxicology. However, little research has been conducted for sources identification and risk management of heavy metals pollution by long-term antimony mining …
The principal ore of antimony is the sulphide stibnite (Sb 2S 3) although the antimony-lead sulphosalt (PB 4FeSb 6S 14) has been worked in some mines. The antimony at the Louisa Mine, in Dumfries and Galloway, is associated with stratiform arsenopyrite-pyrite mineralisation in a Silurian greywacke sequence with similarities to that in the
requirement of antimony in the country is met through imports of its ore and concentrates. HZL is currently operating metal plant having 1,400 TPA antimony concentrate (by-product). During 2018-19, HZL produced 800 million tonne of antimony slag consisting of 60% lead and 20% antimony from pyro-smelter plant. The antimony
ZnO is used as sulfur-fixing agent directly in roasting process to produce Sb 2 O 3 from antimony sulphide ore at 400 ∼ 800 °C. NA: Ouyang et al., 2018: ZnO was used as sulfur-fixing in roasting in presence of carbon to extract Sb from Antimony Sulphide ore at 800 °C. 90.44%: Ouyang et al., 2019
Antimony (Sb) is one of the most commonly used metallic element, with global reserve of 1.9 million tons. According to recent report, almost 80% of Sb production was concentrated in China, Russia, and Bolivia (United States Geological Survey, 2021).By 2020, China was the leading producer of Sb worldwide, accounting for nearly 80,000 metric tons, …
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 concentrations of total …
mony oxide, such as yellow antimony ore [8]. There are more than 120 kinds of ores formed by antimony in nature. Only about ten of them have any industrial value, usually those including stibnite, jamesonite, senarmontite, yellow antimony ore, sulfur and oxygen antimony ore, and native antimony. It fol-
