The correct pair of metal and the ore mineral is
Show Hint
- Nickel - Sphalerite
- Tin - Cassiterite
- Zinc - Pyrolusite
- Lead - Bornite
The Correct Option is B
Solution and Explanation
Step 1: Identifying ore minerals.
- Cassiterite is the main ore mineral of tin, containing tin in its oxidized form.
- Sphalerite is the primary ore mineral of zinc, not nickel.
- Pyrolusite is the ore mineral of manganese, not zinc.
- Bornite is an ore mineral for copper, not lead.
Step 2: Analyzing the options.
(A) Nickel - Sphalerite: Incorrect, as Sphalerite is the ore mineral of zinc, not nickel.
(B) Tin - Cassiterite: Correct — Cassiterite is the principal ore of tin.
(C) Zinc - Pyrolusite: Incorrect, as Pyrolusite is the ore of manganese.
(D) Lead - Bornite: Incorrect, as Bornite is the ore of copper.
Step 3: Conclusion.
The correct answer is (B) Tin - Cassiterite, as Cassiterite is the primary ore of tin.
