Zinc (30)

  1. The element is normally found in association with other base metals such as copper and lead in ores.
  2. Zinc is chalophile, meaning the element has a low affinity for oxides and prefer to bond with sulfides.
  3. Sphalerite (ZnS) – which is form of zinc sulfide, is the most heavily mined zinc (60-62% Zinc).
  4. Other minerals from which zinc is extracted include:
  5. Smithsonite – Zinc Carbonate
  6. Hemimorphite – Zinc Silicate
  7. Wurtzite – Zinc Sulfide
  8. Hydrozincite – basic Zinc Carbonate
  9. Zinc reacts readily with acids, alkalis & other non-metals.
  10. Zinc is the fourth most common metal in use, after Iron, Aluminium & Copper.
  11. Commonly used as an anti-corrosion agent. The protection lasts even after the zinc layer is scratched.
  12. Efficient sacrificial anode in cathodic protection (CP). Also in Electroplating.
  13. Used as an anode material for batteries.
  14. Brass is 3% to 45% Zinc.
  15. Cadmium Zinc Telluride (CZT) is a semiconductive alloy.
