3 0 0 3
UNIT I INTRODUCTION 9
Survey of Indian scene of ores and metallurgical industries with special reference to
electrometallurgical industries. Preparation of cell feed for copper, zinc, aluminium,
magnesium and titanium electrolytic cells. Principles of solvent extraction/ ion exchange for
the recovery of metallic values. Pollution and control measures adopted/recommended in
electrometallurgical Industries like Al, Mg & Cr.

Cell voltage and its components- types of anodes and cathodes-necessity of diaphragms.
Physicochemical properties of molten & aqueous electrolytes like conductivity,
decomposition potential, density etc. Current and energy efficiency- features of aqueous and
molten salt electrolysis distinction between electro winning and refining. Anode effect.

Electro winning of zinc, copper and nickel. Operating conditions for electro winning of
copper and Nickel. Electro refining of silver, lead and copper- periodic current reversal
technique. Electrolytic metal powders-principles, preparation and characterization.
Secondary recovery of metals-Importance and approaches with examples of zinc and
copper.

electrolyte, Brief discussion on (anodes and) cathode pot construction, and reactions. Start
up and operation of Cell- anode effect. Koope’s three layer process. Dow, I.G. and other
types cells for production of Magnesium. Interference of impurities like moisture and sludge
formation. Electrowinning of sodium, calcium, misch metal and titanium. Operating data for
production of lithium and zirconium.- refining of titanium.
