Question

Which of the following pairs is correct with respect to ores and the metals present in these ores?

1. A. Sulphate ores ; Iron (Iron pyrites, FeS2)
2. B. Oxide ores ; Zinc (Hemimorphite, 2ZnO.SiO2.H2O)
3. C. Halide ores ; Silver (Horn silver, AgCl) (Correct answer)
4. D. Silicate ores ; Lead (Anglesite, PbSO4)

Correct Answer

Option C — Halide ores ; Silver (Horn silver, AgCl)

Detailed Solution & Explanation

The correct answer is Halide ores ; Silver (Horn silver, AgCl).

Key Points

• Horn silver (AgCl) is a halide ore of silver.
• Iron pyrites (FeS2) is a sulphide ore.
• Hemimorphite is a silicate ore of zinc.
• Anglesite (PbSO4) is a sulphate ore of lead.
