The major component of which of the following ore is sulphide based mineral?

Question

In the electrolytic refining of a metal M, what would you take as the anode, the cathode and the electrolyte?

Answer 1

To determine which ore has sulphide-based minerals as its major component, let's examine each option:

Siderite: This ore is primarily composed of iron carbonate (FeCO₃), not a sulphide.
Sphalerite: This is a zinc ore with the chemical formula ZnS. It is indeed a sulphide mineral.
Malachite: This ore is primarily copper carbonate hydroxide [Cu₂(CO₃)₂(OH)₂], not a sulphide.
Calamine: Calamine generally refers to the mineral zinc carbonate (ZnCO₃) or zinc silicate (Zn₄Si₂O₇(OH)₂·H₂O), neither of which are sulphides.

Based on the chemical compositions of the options, only Sphalerite is a sulphide-based mineral. Therefore, the correct answer is Sphalerite.

Thus, the major component of the ore Sphalerite is a sulphide-based mineral, represented by the chemical formula ZnS.

Answer 2

Based on the chemical compositions of the options, only Sphalerite is a sulphide-based mineral. Therefore, the correct answer is Sphalerite.

Thus, the major component of the ore Sphalerite is a sulphide-based mineral, represented by the chemical formula ZnS.

The Correct Option is B
