Two minerals (X) and (Y) are concentrated by floth floatation process. On roasting mineral (X) gave a shining liquid metal (Z ) while mineral (Y) under similar condition gave a metal oxide (P) which was yellow when hot and while when cold. Reduction of the oxide (P) withe coke gave metal (Q). Identify the minerals (X) and (Y), the oxide (Z) and metals (P) and (Q).

Explanation

To solve the given problem, we need to identify the minerals (X) and (Y), as well as the metals (Z), (P), and (Q) based on the roasting and reduction processes described. Let's break it down step by step.

### Step-by-Step Solution:

1. **Identify the Minerals (X and Y)**:
- The problem states that both minerals (X) and (Y) are concentrated by the flotation process. This suggests that both are likely sulfide ores.
- **Hint**: Look for common sulfide ores that are processed using flotation.
