General Principles and Processes of Isolation of Elements — NEET/JEE Questions, Notes & Weightage
Class 12 Inorganic Chemistry NEET weightage: Low 29 questions
Covers metallurgy — ore concentration, extraction methods (reduction, electrolytic refining), and thermodynamic/electrochemical principles behind metal extraction (Ellingham diagrams). A compact, lower-priority chapter, but extraction-method matching (which metal uses which process) is occasionally tested.

Frequently asked questions
Are Ellingham diagrams tested in depth?
Only at a conceptual level for most NEET/JEE purposes — knowing what the diagram shows (feasibility of reduction at a given temperature) is usually sufficient.
What metal-extraction fact is asked most?
Matching a specific metal (iron, copper, aluminium, zinc) to its primary extraction/reduction method is the most common question format.
