Sulphide ores are common for the metals

Options

A. `Ag, Cu and Pb`
B. `Ag, Cu and Sn`
C. `Ag, Mg and Pb`
D. `Al, Cu and Pb`

Answer

To solve the question regarding which metals have common sulphide ores, we can follow these steps:

### Step 1: Identify Common Sulphide Ores
Sulphide ores are minerals that contain metal sulfides. The most common metals that are extracted from sulphide ores include silver (Ag), lead (Pb), and copper (Cu).

### Step 2: List the Sulphide Ores for Each Metal
1. **Silver (Ag)**: The sulphide ore is **Argentite**, which has the chemical formula **Ag₂S**.
2. **Lead (Pb)**: The sulphide ore is **Galena**, which has the chemical formula **PbS**.
3. **Copper (Cu)**: The sulphide ore is known as **Chalcocite**, which has the chemical formula **Cu₂S**.

### Step 3: Conclusion
From the above information, we conclude that sulphide ores are common for the metals Silver (Ag), Lead (Pb), and Copper (Cu). The corresponding sulphide ores are Ag₂S, PbS, and Cu₂S respectively.

### Final Answer
Thus, the metals for which sulphide ores are common are **Ag, Pb, and Cu**.
