B.Tech III Year II Semester (R16)
Expose the mining engineer to various aspects of beneficiation of ores
and industrial minerals for value addition. To introduce mineral processing characteristics of minerals, “concentrations, physico-chemical principles, flow sheets for beneficiation of various minerals.
Mining Engineering student would be exposed to the practices of
beneficiation ores and coal which is important for value upgradation for main product and for byproduct recovery for the societal use. Student can get the opportunity to know various techniques of mineral processing including theory, application and their limitations and environmental implications.
Introduction: Scope, objectives and limitations of mineral processing, liberation and beneficiation characteristics of minerals and coal. Comminution: Theory and practices of crushing and grinding; different types of crushing an grinding equipment’s – their applications and limitations.
Liberation- importance and determination of liberation size, Crushing- fundamentals, construction and operational features of primary and secondary crushers. Jaw, Gyratory, cone and roll crushers. Grinding- theory and practice, Ball & Rod Mills- construction and operation. Laboratory sizing and industrial screening including screen efficiency.
Size Separation: Laboratory size analysis and interpretation; settling of solids in fluids; industrial screens, mechanical classifiers and hydro cyclones. Gravity Concentration Methods: Jigging, Heavy media separation, flowing film concentrators – theory, applications and limitations.
Froth Floatation: Physico-chemical principles, reagents, machines, floatation of sulphides, oxides and coal. Electrical Methods of Concentration: Principles, fields of applications and limitations.
Magnetic methods of concentration Principles, Fields of Application and Limitation Flow Sheets: Simplified flow sheets for coal, copper, zinc, lead, gold, chromite, iron, and manganese ores.
