Question

Trace elements that show affinity for sulphide minerals are called

• A. Siderophile
• B. Chalcophile
• C. Lithophile
• D. Hydrophile

Hint:

Remember: "Chalco" refers to sulfur-based compounds — chalcophile means sulfur-loving.

Answer 1

The Correct Option is B

Step 1: Siderophile elements bond with metallic iron, not sulphides, so rule that out.
Step 2: Lithophile elements bond with oxygen in silicates, also ruled out.
Step 3: "Hydrophile" is not a recognised geochemical affinity class.
Step 4: Correct answer, chalcophile, elements with affinity for sulphide minerals.
