The Goldschmidt Alumino-Thermite process is employed to extract transition metals like Chromium and — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Cr and Mn oxides have high lattice energies and cannot be easily reduced by Carbon. Furthermore, high-temperature carbon reduction often yields stable metal carbides instead of pure metal. Aluminium is highly electropositive with a massive affinity for oxygen, making the highly exothermic thermite reduction thermodynamically favorable.
