Antimony: The hidden metal fuelling global competition
China is a net importer of antimony metal. Currently, 86% of Australia's antimony exports are sent to China for processing. Investing in processing capacity and infrastructure for lower-grade antimony products may offer limited strategic value for the United States, as these products will still be available under China's restrictions.

The exposure to and health effects of antimony
INTRODUCTION. Antimony (Sb) (atomic number 51; atomic mass 121.75 g/mol; density 6.684 g/cm 3; melting point 631°C) occurs naturally as a sulphide ore, stibnite (Sb 2 S 3) and valentinite (Sb 2 0 3).The traditional method of treating the ore is to roast it with charcoal or coke and collect the volatile oxide fume (Sb 4 O 6) from which pure …
