Antimony (Sb) is a silver-white brittle solid or a dark-gray, lustrous powder. It can be harmful to the eyes and skin. Antimony can also cause problems with the lungs, heart, and stomach. Workers may be harmed from exposure to antimony and its compounds. The level of exposure depends upon the dose, duration, and work being done.Get Price
Antimony (Sb) is a hard, brittle, silver-white metal with a relatively high specific gravity (6.69) and a relatively low melting temperature. Antimony is a constituent in some alloys. The presence of this metal hardens the alloy, lowers the melting point, and decreases contraction during solidification. The metal’s main use is to impart stiffness and hardness to lead alloys. Antimony ...Get Price

With the increase of mining depth, rockbursts have become important safety problems in Zhazixi Antimony Mine, where overlying strata exceed 560 m. Due to the small spacing between the steeply inclined veins, mining activities have great influences on rockbursts of adjacent veins.

The first record of primary antimony mining in Alaska was the Sliscovich Mine about 30 miles northeast of the famed gold mining town of Nome. First opened in 1906, Sliscovich was positioned to provide a domestic source of antimony at the onset of World War I, which sparked stibnite mining across much of …Get Price
When companies break up materials during mining, the dust can release a variety of heavy metals commonly associated with health problems. As dust, these minerals (such as the asbestos-like mineral riebeckite) can be absorbed into lung tissue, causing problems like pneumoconiosis and silicosis, commonly known as Black Lung (Paul & Campbell, 2011).Get Price
Aug 21, 2011 Arsenic and antimony contamination is found at the Pezinok mining site in the southwest of the Slovak Republic. Investigation of this site included sampling and analysis of water, mineralogical analyses, sequential extraction, in addition to flow and geochemical modeling. The highest dissolved arsenic concentrations correspond to mine tailings (up to 90,000 μg/L) and the arsenic is present ...Get Price

Antimony (Sb) is a harmful element, and Sb pollution is one of the typical environmental issues in China, meaning that understanding of the geochemical behaviors of Sb is the key to control the fate of environmental Sb pollution. Sb tends to migrate in soluble form in the water-sediment system, but the fate of dissolved Sb is poorly known.Get Price
Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle the non metallic form is a grey powder. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis. Antimony and some of its alloys expand on cooling. More +Get Price
