### Step-by-Step Solution 1. **Identify the Ore and Its Concentration Process:** - The ore in question produces sulfur dioxide upon heating, indicating it is likely a sulfide ore. To concentrate this ore, the **froth flotation process** is recommended. This process separates the ore from impurities (gangue) based on differences in their wetting properties. 2. **Describe the Froth Flotation Process:** - In the froth flotation process, the crushed ore is mixed with water and chemicals that preferentially bind to the sulfide minerals. Air is then bubbled through the mixture, creating froth. The sulfide minerals attach to the bubbles and rise to the surface, forming a froth that can be skimmed off, leaving behind the gangue. ...
