|Occurrence of Metals
||Occurrence (ores) of Al, Cu, Zn and Fe.
|Concentration of Ores
||Principles and methods of extraction: concentration of ores – hydraulic washing, magnetic separation, froth floatation, leaching -of alumina from bauxite, roasting and calcination –examples.
|Extraction of Crude Metal from Concentrated Ore
||Extraction of Crude Metal from Concentrated Ore.
|Thermodynamic Principles of Metallurgy
||Principles of extraction of aluminium, copper, zinc, iron: highlight the principle of extraction of iron from its oxide using Ellingham diagram.
Extraction of iron from its oxides – blast furnace – diagram, reactions, equations.
|Electrochemical Principles of Metallurgy
||Extraction of aluminium from purified alumina.
||Oxidation-reduction – extraction of gold.
||Principles and examples each for distillation, liquation, electrolytic method, zone refining, vapour phase refining- details for Mond’s and Van Arkel processes.
