Question

Cinnabar is an ore of
1. Hg
2. Zn
3. Ag
4. Cu

Answer 1

Correct Answer - Option 1 : Hg

Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit.

Cinnabar is the bright scarlet to brick-red form of Mercury(II) sulfide (HgS).

• It is the most common source ore for refining elemental mercury (Hg)
• It is the historic source for the brilliant red or scarlet pigment termed vermilion and associated red mercury pigments.

Hence we can conclude that Cinnabar is an ore of Hg.

• Zn ore: Calamine (ZnCO3), is most common zinc ore.
• Ag ore: Various ores such as Argentite (Ag₂S), Chlorargyrite ("horn silver," AgCl), and Galena (a lead ore) often containing significant amounts of silver.
• Cu ore: Pyrite (FeS2), Chalcopyrite (CuFeS2) Chalcocite (Cu2S), Covellite (CuS), Bornite (Cu5FeS4), Tetrahedrite ((Cu,Fe)12Sb4S13) and Enargite (Cu3AsS4)
