Explanation
To solve this problem, we need to match the processes in Column I with their corresponding applications in Column II.Let's analyze each process:(a) Cyanide process:• This process is used for the extraction of gold (Au).• Gold is leached from its ore using a cyanide solution, forming a soluble gold-cyanide complex.• Therefore, (a) matches with (iv) Extraction of Au.(b) Froth flotation process:
