A Brief History of Antimony in China | Amspec
In 1908-1914, over 80% of the antimony for use was from China. During the years 1922-1931, it accounted for 73%. The three decades following World War II mark an era in which China's position in the global antimony market slowly declined. The downward trend bottomed-out in the '70s with China only producing about 25% of global output.
