Additional information
Unit content:This unit mainly consists of lectures and tutorial/workshop and laboratory sessions.
Lectures will cover basic principles for the beneficiation of a target metal or mineral which will include the fundamentals of comminution (crushing and grinding), gravity, electrostatic, screening, and the importance of representative sampling, sampling methods and the amount required.
The laboratory experiments cover a wide range of crushing, sizing, sampling and separation techniques. The experiments are: 1) Determination of Bond Work Index; 2) Fine Particle Sizing by Cyclosizer, Andreasen Pipette and Laser-sizer; 3) Fine Particle Classification; 4) Sampling Techniques; 5) Gravity Separation by Tabling and Spirals; 6) Float and Sink Analysis of Coal; 7) Mineral Concentration by Dry Magnetic and Electrostatic Separation.
