An ore on heating in air produces sulphur dioxide. Which process would you suggest for its concentration? Describe briefly any two steps involved in the conversion of this concentrated ore into related metal.

Explanation

To solve the question, we will follow these steps:

### Step 1: Identify the Concentration Process
The ore in question produces sulfur dioxide when heated in air, indicating it is likely a sulfide ore. The suitable method for concentrating sulfide ores is the **froth flotation method**. This method separates sulfide ores from impurities based on their hydrophobic properties, where sulfide ore particles attach to air bubbles and rise to the surface, while impurities remain submerged.

### Step 2: Describe the Conversion of Concentrated Ore into Metal
Once we have concentrated the ore, we need to convert it into the metal. This involves two main steps:
