Which of the following process is not associated with steel making? — d and f Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Identify the metallurgical processes used in steel production. Step 2: The Bessemer process, Open-Hearth process, and Kaldo process are well-known industrial methods used to refine pig iron into steel by oxidizing impurities. Step 3: Auto-oxidation is a chemical process involving spontaneous oxidation of a substance in the presence of oxygen (often used in the production of hydrogen peroxide), and is not associated with steelmaking. Thus, option (d) is correct.
