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

Explanation

To determine which scrap metal, zinc or iron, is more suitable for reducing low-grade copper ores, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Copper Ore**:
- Copper ores, such as chalcopyrite (CuFeS₂), are often leached to extract copper ions (Cu²⁺) which can then be reduced to metallic copper.

2. **Understand Reduction**:
