JNTUK B.Tech Principles of Extractive Metallurgy gives you detail information of Principles of Extractive Metallurgy R13 syllabus It will be help full to understand you complete curriculum of the year.
Course objective: The main scope and objective is to give an overall view on the fundamental aspects of metal extraction processes.
UNIT-I : Learning objective: The unit aims to discuss unit processes during the metal extraction
Introduction: Classification of ores, advantages and disadvantages of unit processes in extractive metallurgy. Calcination.
UNIT-II : (Learning objective: Deals with different types of roasting processes)
Roasting: Types of roasting: Oxidizing, sulphatising and chloridizing. Simple equations/reaction. Roasting furnace: Multiple hearth roaster, flash roasting, fluidized bed roasting, blast roasting. Sintering and pelletisation
UNIT-III : (Learning objective: The unit outlines different reduction processes and also discusses the Ellingham diagrams)
Smelting, smelting furnaces and slags: Principles of reduction and matte smelting with examples. Reverberatory, BF and electric smelting. Flash smelting. Classification, properties importance of Ellingham diagrams for oxides and sulphides and ellinghams limitations.
UNIT-IV : (Learning objective: The main objective is to describe the principles of leaching and associated hydrometallurgy)
Hydrometallurgy: Advantages and disadvantages. Flowchart. Principles and types of leaching. Solution purification by ion and solvent exchange. Metal recovery from leach solution by cementation.
UNIT-V : (Learning objective: The main objective is to describe the principles of electrometallurgy and electrowinning) Classification of electrometallurgy, advantages and disadvantages electrometallurgy. Electrolytic cell-Anodic and cathodic reactions. General discussions on the electrowinnig of metals.
UNIT-VI : (Learning objective: The main objective is to describe the methods of refining)
Principles of Refining: Fire refining. Distillation, liquation, electro-refining and zone refining.
(Assessment: The student should be evaluated based on the assignments and objective tests. Emphasis should be given by conducting tutorial classes (with special focus on academically weak students) at the end of each unit).
