Which methods would you recommed for the purification of impure metals such as zinc. Copper and germanium metals ?

Explanation

To purify impure metals such as zinc, copper, and germanium, we can use the following methods based on their properties:

### Step-by-Step Solution:

1. **Purification of Zinc:**
- **Method:** Fractional Distillation
- **Reason:** Zinc has a relatively low boiling point (around 907 °C). In fractional distillation, the impure zinc is heated, and as it vaporizes, it can be separated from impurities that have higher boiling points. The vapor is then condensed back into liquid zinc, resulting in a purer form of the metal.
