Workers can be exposed during smelting, manufacture of antimony compounds, glass, textiles, and batteries, and electrical-waste processing. Non-occupational exposures occur via water, air, soil, consumer products, and tobacco. Weapons-grade tungsten (with nickel and cobalt) alloy is used in armour-penetrating munitions.

A body of rich tungsten ore was also found and mined. During World War II, Stibnite produced ninety-eight percent of America's antimony in addition to a large proportion of the nation's tungsten. Both metals were vital to the production of military machinery and weaponry. The rich Stibnite Mine tungsten ore was exhausted by the end of the war ...
The Hillgrove gold–antimony–tungsten occurrences have strong affinities to many other orogenic gold-antimony deposits elsewhere, particularly in New Zealand, except that the ore mineral assemblage is telescoped, with earlier deeper level mineralisation overprinted at the same structural level by later, shallower mineralisation.
The most common antimony ore mineral is stibnite (Sb2 S3 ), but more than 100 other minerals also contain antimony. The presence of antimony in surface waters and groundwaters results primarily from rock weathering, soil runoff, and anthropogenic sources. Global emissions of antimony to the atmosphere average 6,100 …
Antimony ore is often produced as coarse monomer crystals or massive aggregate crystals. Due to the large differences in color, luster, and shape between antimony-containing minerals and gangues in antimony ore, it is convenient to hand-select. ... For example: tungsten-antimony-gold polymetallic sulfide ore, antimony-arsenic-gold …
However, the main antimony ore producing countries are China, Russia, and South Africa [10]. China's antimony reserves and production rank first in the ... spar, tin, and …
Tungsten (also called wolfram) [10] [11] is a chemical element; it has symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was …

Antimony is a non-renewable strategic mineral resource and an indispensable and important raw material for modern industrial development. With the high-intensity resource mining in recent years, the consumption of antimony resources is too large. Antimony beneficiation methods are important to improve the recovery rate of …
From 1941 to 1945, Stibnite Mine produced more antimony and tungsten than any other mine in the U.S. – accounting for 90% of the antimony and 40% of the …
The fluids related to tungsten mineralization for the NaCl-H 2 O system had a medium-to-high temperature and low salinity, while the fluids related to tin mineralization for the NaCl-H 2 O system had a high temperature and medium-to-low salinity. The results of this study suggest that fluid cooling is the main mechanism for the precipitation of ...
Antimony ore has two types of mineralization, i.e., hydrothermal and placer antimony deposits, mainly distributed in Myanmar's Moulmein, Wang- Chin in Thailand and Bac Can-Cao Bang in northeastern Vietnam. ...

The Shalagang Sb deposit is located at 40km southeast of the Ranba complex dome at the Northern Himalaya area in China. At least four mineralization styles are recognized in Northern Himalaya: (1) Au deposits; (2) Sb-Au deposits; (3) Sb deposits and (4) Pb-Zn (Ag, Sb) deposits. Shalagang is one of representative vein type antimony deposits that have …
