• 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.
