Mechanisms of size reduction, fragmentation theories and energy requirements for size reduction. Work index of ores. Type of crushers and their integration in circuit design.
Milling, screening and classification
* Milling - theoretical basis, mill rotation and critical speed aspects. Type of mills and comminution circuit arrangements.
* Screening - principles, type of screens and selection criteria.
* Classification - principles, type of classifiers, design features.
Common mineral beneficiation techniques - gravity, magnetic, electrostatic and physicochemical (froth flotation), hydrometallurgy - theory and associated equipment.
Examples of unit operations. |
|
Learning outcomes of the course :
|
| The objective is to introduce the theoretical aspects of common mineral processing techniques and the associated equipment utilized nowadays in mining and extractive metallurgy practices. Students will be acquainted with the basics of solids separation principles when applied to ores and minerals, from the mine down to concentrates production. They will be immersed in team working environment.
The course is designed to enable students to perceive right from the beginning the challenges facing the modern mineral processing industry in terms of equipment development, circuit modeling and situation and geometallurgical consideration.
At the end of this introductory course, students will possess the pre-required background and will be prepared to follow the in-depth basic (S8) and advanced and specialized courses (S9) in mineral processing. |
