Last year, China accounted for 48% of global mined output of antimony, according to the US Geological Survey (USGS). Gary Evans, the co-chief executive officer of United States Antimony, said that ...
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 first record of primary antimony mining in Alaska was the Sliscovich Mine about 30 miles northeast of the gold rush 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, an event that sparked stibnite mining across much of Alaska.
