It was found that some of the medicinal plants accumulate increased amounts of toxic elements like Cd or Pb. Less is known about the accumulation of other hazardous elements like arsenic (As) and antimony (Sb) in these species. The present paper investigated selected medicinal plants naturally growing on old mining sites in Slovakia, Central Europe, contaminated by As and Sb. Both these ...

Jan 06, 2020· The average Rotterdam price for antimony metal during December 2019 was $6,027.12 per metric ton or $2.818 per pound. CEO John Lawrence said "We are excited that after years of permitting, metallurgical research, exploration, mining, building a flotation mill that the final phase using cyanide leaching to recover the gold and silver lost in the flotation process by is being verified."
Many crops cultivated in mining areas have been found to accumulate high levels of antimony (Sb) in their edible parts, thereby causing potential risks to human health. Understanding the behaviours of Sb in plants is important, particularly the mechanisms involved in its uptake, toxicity, detoxification and accumulation in crops.

The distribution, bioavailability, and accumulation of antimony (Sb) at the interface of rhizospheric soils and indigenous plants from a large Sb mining/smelting area in Southwest China were explored. Results showed that the local soil was severely polluted by Sb, and the aluminum magnesium silicate minerals and the carbonate fraction may mainly contribute to bound Sb.

The history of the antimony industry of China dates back to 1897 when the Tai Shing Co. was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude; and in 1908 the Wah Chang Mining & Smelting Co. was formed for the smelting and refining of the ore and crude to regulus.
Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl.
