stibnite roasting process

  • Antimony revisited

    Jul 01, 2008The art of preparing pure metallic antimony is described in the 17th century work Triumphal chariot of antimony by Basil Valentine which, though published in 1604, is thought to have been written about 250 years earlier. 4 The process involved roasting stibnite to form the oxide, followed by reduction with carbon to obtain the free element. In 1615 German chemist and physician, Andreas Libavius

  • metal

    A metal is a substance characterized by its strength and its ability to conduct heat and electricity, as well as by numerous other physical and chemical properties. At room temperature metals are solid (with the sole exception of mercury). Most metals have a silvery gray, shiny appearance; almost all can be drawn smoothly into wire and hammered into sheets.
