Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting. The performance of most of …
Noble antimony is the carrier of precious metals in the antimony smelting system and has a very high added value. This study proposes a novel, green, and effective vacuum gasification process for purifying antimony and recovering precious metals from noble antimony. Saturated vapor pressure and separation coefficients (β) were used to …
Antimony is a carcinogen, and toxic to the heart, lungs, liver and skin. Long term inhalation causes chronic bronchitis and emphysema. The industry will say that although antimony is used as a catalyst in the production process, it is "locked" into the finished polymer, and not a concern to human health.
Overall, China's antimony production had increased rapidly in the last decade to meet both domestic (50–65%) and foreign demands (35–50%). The accumulated antimony consumption reached 1457 kt in China during this study period, in which over one third of such antimony resource was purchased from the international markets (38%, …
