Which of the following is not a sulphide ore?
Which of the following is not a sulphide ore?
Updated On: Apr 5, 2025
- Pyrolusite
- Galena
- Cinnabar
- Copper iron pyrites
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Sulphide ores are those ores that contain sulphur in combination with a metal.
Galena (PbS) is a sulphide ore of lead.
Cinnabar (HgS) is a sulphide ore of mercury.
Copper iron pyrites (CuFeS_2) is a sulphide ore of copper and iron. However, pyrolusite (MnO_2) is not a sulphide ore; it is an oxide ore of manganese.
The correct option is (A): Pyrolusite
