Question

How is zinc extracted from calamine? Also write chemical equations.​

Answer 1

Answer:

zinc is extracted from calamine through calcination process were it is heated under limited presence of oxygen to form ZnO and then the oxide is removed and further refined to get zinc

Answer 2

Zinc extraction from calamine

Explanation:

• This is a 2 step process.

• When calamine (ZnCO₃) is heated in absence of air, it produces zinc oxide (ZnO) and carbon dioxide (CO₂)

• Then zinc oxide is heated with carbon thus produces zinc metal and carbon monoxide.

         I) ZnCO₃⇒ ZnO+CO₂

         II)ZnO+C⇒Zn+ CO
