Key Topics to Revise

1

Occurrence of Metals in Nature

  • Earth's crust is the major source of metals; seawater also contains soluble salts
  • Metals like gold (Au), silver (Ag), and copper (Cu) exist in free state (native) due to low reactivity
  • Most metals occur in combined form due to higher reactivity
2

Activity Series and Metal Reactivity

  • Metals arranged in decreasing order of reactivity: K, Na, Ca, Mg, Al | Zn, Fe, Pb, Cu | Hg, Ag, Pt, Au
  • High reactivity metals (K, Na, Ca, Mg, Al) never found in free state
  • Moderately reactive metals (Zn, Fe, Pb) found mainly as oxides, sulphides, carbonates
3

Extraction of Metals - Three Main Stages

  • Stage 1: Concentration or Dressing - removes gangue from ore
  • Stage 2: Extraction of crude metal - converts ore to metal
  • Stage 3: Refining or purification - removes impurities from crude metal
4

Concentration Methods

  • Hand picking: Based on color, size differences
  • Washing: Based on density differences - lighter impurities washed away
  • Froth flotation: For sulphide ores - uses wetting property differences
