The oxidation states and host phases of Sb and As in soil samples of mine tailing (Ichinokawa mine, Ehime, Japan) and in laboratory soil-water systems were determined by X-ray absorption fine structure (XAFS) spectroscopy. HPLC-ICP-MS was used for speciation of Sb and As in soil water. In the Ichino …

1. Introduction. Antimony (Sb) is a naturally occurring metalloid widely used in industrial products such as lead-acid batteries and flame-retardants (Anderson, 2001).Sb and its compounds are suspected carcinogens (De Boeck et al., 2003) and have been listed as priority pollutants by the US Environment Protection Agency (USEPA, 1979).The rapid growth of Sb …

Read the concordances about Antimony – it is actually referring to the use of it as kohl eyeliner. The context of this passage describes the church as a barren woman who is not left bereft, but is to become the mother of many children, and who is not disgarded, but is to be the wife to her Maker, her husband.

As China curbs exports of the strategic and critical metalloid, America's Last Frontier reemerges as potential domestic supplier. China's coming state-controlled restrictions on antimony exports has significantly elevated the criticality and price of this semi-metal that is already a top concern from many officials within the U.S. Department of Def...

Antimony is a metallic element (chemical symbol 'Sb') that occurs primarily as the sulphide mineral stibnite, which is the principal ore for antimony mining operations worldwide. The extraction of antimony involves both underground and surface mining methods, depending on the ore deposit's characteristics.

Consolidated Murchison Limited is the only primary producer of antimony in South Africa, producing approximately 18 per cent of the total world production. This paper gives a technical review of the history, occurrence, mining, and metallurgy of antimony at Consolidated Murchison. World antimony markets are also discussed, together with the end-uses.

The concentrations of Total Sb in the iron-free and iron-added groups were largely decreasing in 0–48 h, and tended to be stable in 48–72 h (Fig. 1 D,F), which was caused by the adsorption of antimony by S. oneidensis.SEM results of S. oneidensis before and after reaction with antimony in the iron-free group were shown in Fig. 2 A,B. After the reaction with …

1. Introduction. Antimony (Sb) is widely present in environmental compartments (Wilson et al., 2010).Generally, concentrations of Sb in the earth's crust are estimated to be < 0.3 mg kg −1 (Wedepohl, 1995), and the background concentrations of Sb in soils are present in the span < 0.3–8.4 mg kg −1, but it tends to be concentrated in the surface soils (Hammel et al., …

Antimony, a unique metalloid, finds widespread applications in various industries. Sb plays a role in the manufacturing of flame-retardant, spans plastics, textiles, and electronics (Nishad and Bhaskarapillai, 2021). Furthermore, Sb enhances properties in lead (Pb)-acid batteries, alloys, and solders and is used as a fining agent in glass ...

Antimony comes under group 15 of the periodic table with ground state electronic configuration [Kr]4d 10 5s 2 5p 3. 121 Sb (57.21% abundance) and 123 Sb (42.7% abundance) are the two stable isotopes of antimony. Antimony can possess different oxidation states (such as +5, +3, 0, −3 and −5), but generally found to exist in the +3 and + 5 oxidations states …

Antimony (Sb) is ubiquitous throughout the environment as a result of natural processes and human activities. In China, superlarge-, large and medium-sized Sb deposits are concentrated in the Guangxi (34.4%), Hunan (21.2%), Yunnan (12.2%) and Guizhou (10.2%) provinces. Due to Sb mining and smelting …
