ANTIMONY HAS BILLION-DOLLAR POTENTIAL IN TAJIKISTAN
Antimony hit its previous price peak in 1995-96, at $5,000 per metric ton, or about $2.27 per pound. The price then collapsed by December 2001 to $1,000/tonne, 45 cents/lb. The revival of Chinese demand, outstripping domestic production, started the price moving upward since then. It reached $5,350/tonne, $2.43/lb, in July 2007.
Antimony Statistics and Information | U.S. Geological Survey
Estimates of the abundance of antimony in the Earth's crust range from 0.2 to 0.5 parts per million. Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver.
