  • Calaverite Molecular Formula- AuTe2
  • Calaverite Color is Brass-yellow to silver-white.
  • Calaverite mineral is a combination of tellurium and gold.
  • Calaverite other name gold telluride.
  • It is an uncommon telluride of gold a metallic mineral  with approximately 3% of the gold replaced by silver.
  • The minor sources of gold  in general is Calaverite and sylvanite major telluride ores.
  • Calaverite occurs as monoclinic crystals in nature.
  • Calaverite has a specific gravity of 9.35 and a hardness of 2.5.
  • Calaverite can be dissolved in concentrated sulfuric acid.
  • Calaverite also dissolved in hot sulfuric acid and  leaving a spongy mass of gold in a red solution of tellurium.
  • Calaverite generally corresponded with the gold-silver telluride mineral sylvanite.
  • It is in lower percentage of ionic silver in place of ionic gold.
  • Calaverite is monoclinic and isomorphous with sylvanite.
  • Calaverite commonly occurs in the presence of sulfide minerals.
  • Telluride minerals are dissolved completely by  leaching solutions.
  • The classic old mortar and pestle was the method used by early day miners to crush their ore specimens for testing.
  • The market demand for calaverite in china is 550 GW of new capacity is expected to be installed in China between  2010 and 2020.
