MetallurgyHandwritten Notes
Metallurgy rewards memorisation of named extractions and Ellingham diagrams — the rest is principle-based. These handwritten notes by Paaras Sir cover ore concentration, reduction, refining, and the extraction of Fe, Cu, Al, and Zn step by step.

Frequently Asked Questions
Is the Ellingham diagram explained?+
Yes — the ΔG° vs T plot is interpreted line-by-line, including the role of CO and the kink in the carbon line above 1000 K, with worked reasoning for picking C vs H2 vs Al as reductant.
Do the notes cover the Hall–Héroult process?+
Yes. The full electrolytic cell setup for Al extraction (cryolite + Al2O3 melt, carbon anodes, steel cathode) is drawn with the cell reactions.
Is the van Arkel method included?+
Yes — both the van Arkel (ZrI4 / TiI4 thermal decomposition) and Mond's process (Ni(CO)4) refining methods are covered with reaction equations.
