• Improved gold and silver extraction from a refractory

    Prior to the leaching tests, detailed mineralogical studies were performed to identify the presence and association of gold and silver within the ore. Because of the intimate association of gold and silver found with antimony minerals, the leaching behavior of antimony from the ore was also monitored during the alkaline sulphide leach tests.

    Stibnite is also the mineral name for antimony ore. Mining for gold and antimony began at Stibnite in 1931. Later a body of rich tungsten ore was found. During World War 11, Stibnite produced ninetyeight percent of America''s antimony, and much of her tungsten. Both metals were vital for making machines and weapons for fighting the war.
