CHZ 521E - Ultrafine Grinding Technologie

Course Objectives

1. The purpose of this course is to teach students how to use ultrafine grinding technology for industrial mineral evaluations and energy production plants,
2. To teach students how to use grinding processes for the beneficiation techniques of some minerals which are liberated at the ultrafine size and for hydrometallurgical processes, and understand the classifications techniques, explain the differences of the other size reduction processes,
3. To evaluate and study project of ultrafine grinding plants
