1. Chlorine

2. Bromine

3. Iodine

4. Fluorine

Q.

Given below are some statements contrasting Hydrometallurgy and pyrometallurgy. Which of the following are the advantages of Hydrometallurgy (leaching)?

1. As compared to pyrometallurgy, hydrometallurgy offers excellent chemical selectivity and flexibility.

2. Hydrometallurgy predominantly involves much lower temperatures than pyrometallurgy.

3. Since Hydrometalurgy is employed at relatively lower temperatures, it involves very dilute solutions and slow reaction rates.

4. Unlike pyrometallurgy, leaching doesn't produce huge volumes of corrosive gases that pollute the environment.
