  • CBSE Class 12 Chemistry Notes Ores and Metallurgy

    Apr 22 2019 · The roasting of an ore of a metal usually results in conversion of the metal to the oxide. Why does the roasting of cinnabar HgS produce metallic mercury rather than an oxide of mercury Solution Since Hg lies much below in the electrochemical series hence HgO is further reduced to Hg. HgS → HgO → Hg. Illustration 2. Ore dressing of iron
