Extraction of Metals from Ores - GeeksforGeeks

Oct 05, 2021  Extraction of Mercury: Cinnabar (HgS), a sulphide ore, is the most common mercury ore.The following steps can be used to extract the metal (Hg) from the ore. Step 1: In the air, roast concentrated mercury (II) sulphide ore. Roasting is the process of turning a sulphide ore into its equivalent metal oxides by rapidly heating it in the presence of air. . As a result, concentrated mercury
