🧠 The Purification Palette
Metallurgy isn't just about heat; it's about using the unique physical and chemical properties of metals to sieve out impurities. This match-the-column tests your knowledge of specific refining techniques.

🗺️ The Match-Up
- (A) Boron: Semi-metals and elements requiring ultra-high purity (like Silicon or Germanium) are refined using Zone Refining. This method relies on the principle that impurities are more soluble in the melt than in the solid state.  (iv)
- (B) Tin
