antimony: new smelter to open in oman. additional feedstock will reportedly be sourced from tajikistan and russia. output will consist of antimony metal regulus european standard grade 1 and 2 and a low lead antimony trioxide branded as tri-star ato for the european flame retardant market as well as the wider global chemical sector. all production is expected to be exported.
antimony is a chemical element with the symbol sb and atomic number 51. a lustrous gray metalloid it is found in nature mainly as the sulfide mineral stibnite. antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics often known by the arabic name kohl. metallic antimony was also known but it was erroneously identified as lead upon its discovery. the earliest known description of the metal in the west was written in 1540 by vannoccio biringuc
antimony is chalcophile occurring with sulfur and the heavy metals lead copper and silver. over a hundred minerals of antimony are found in nature. stibnite sb2s3 is the predominant ore mineral of antimony. the most important use of antimony metal is as a hardener in lead for storage batteries.
the main suppliers of materials are china russia bolivia and south africa however although the overall antimony market is small by comparison with base metals it is growing in importance. a new report from hexa research points to substantial growth in the antimony tin oxide ato market to 2024.
