Iodine can be separated from sand by sublimation.

Answer

**Step-by-Step Solution:**

1. **Understanding the Components**:
- Identify the two components in the mixture: iodine (I2) and sand. Both are solid substances.

2. **Properties of the Substances**:
- Recognize that iodine is a sublimable substance, meaning it can transition directly from a solid to a gas (vapor) without becoming a liquid first.
- Sand, on the other hand, is a non-sublimable substance, meaning it does not undergo sublimation.

3. **Heating the Mixture**:
- When the mixture of iodine and sand is heated, the iodine will sublime. This means it will turn into vapor while the sand remains solid.

4. **Collecting the Iodine Vapors**:
- The iodine vapors can be collected and then cooled down. When cooled, the vapors will condense back into solid iodine.

5. **Separation of Components**:
- After the heating and condensation process, you will have pure iodine collected and the sand will remain in the original container. Thus, the two substances are effectively separated.

6. **Conclusion**:
- Therefore, iodine can indeed be separated from sand using the sublimation method.
