| Course contents : | This course is dealing with the existing modern mineral processing methods. Basic techniques for bulk solids characterization, particle measurement and their implication to fragmentation, phase's liberation and estimation of separation efficiency are discussed. The principles of size reduction and classification and the associated equipment are covered. The importance of energy reduction in mineral processing is stressed. The mineral separation techniques discussed encompass gravity, magnetic, electrostatic, physicochemical (froth flotation) and hydrometallurgical (in-situ leaching) methods. The principles of their integration in modern ore processing flow-sheets are presented. Finally, examples dealing with the involvement of mineral separation techniques in the niche of materials recovery from secondary resources and industrial wastes are presented. |
|
| Course objective : | The objective of the course is to acquaint the students with the basics of ore and mineral processing techniques utilized in nowadays mining and extractive metallurgy practices. The students will be able to understand the basic principles behind each processing technique and their integration in flowsheets leading to efficient extraction of the valuable components in the ore. The necessity to link applied mineralogy, process technology and economics will be shown. |
|
| Prerequisites : | It is advisable to have knowledge about mineral chemistry and applied mineralogy |
|
| Workshops : | Lab works involving granulometric analysis (sieving), classification, separation (gravity, magnetic, electrostatic ...), froth flotation. Flowsheet design. Calculation - balance, metal grade, recovery. |
|
| Organization : | lectures, lab experiments |
|
| Written notes : | lecture material as pdf files available at the WebCT of the course
