At a site, low grade copper ores are available and zinc and iron scraps are also available. Which of the two scraps would be more suitable for reducing the leached copper ore and why?

Explanation

To determine which scrap material (zinc or iron) would be more suitable for reducing leached copper ore, we can follow these steps:

### Step 1: Understand the Reduction Process
Reduction in metallurgy refers to the process of removing oxygen from a metal oxide or converting a metal ion into its elemental form. In this case, we want to reduce copper ions (Cu²⁺) to elemental copper (Cu).

### Step 2: Identify the Available Materials
We have two materials available for the reduction process:
- Zinc (Zn)
