Match the following from column `I` to column `II`
`{:("Column I" , "Column II"),("Malachite",Fe),("Sphalerite",Ag),("Horn silver", Zn),("Chromite",Cu):}`

Explanation

To solve the problem of matching the ores in Column I with their corresponding metals in Column II, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Ores and Their Chemical Names:**
- **Malachite:** This ore is known as basic copper carbonate. Its chemical formula is \( \text{CuCO}_3 \cdot \text{Cu(OH)}_2 \). It is primarily an ore of copper.
- **Sphalerite:** This ore is also known as zinc blend and is composed of zinc sulfide. Its chemical formula is \( \text{ZnS} \). It is primarily an ore of zinc.
- **Horn Silver:** This ore is known as chlorargyrite, and its chemical name is silver chloride with the formula \( \text{AgCl} \). It is primarily an ore of silver.
