JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objective

This Laboratory course is designed to make the student to understand and

demonstrate the process variables in mineral processing techniques employed. The mineral characteristics like size and size distribution etc. also evaluated.

Course Outcome

The student would gain hands on experience about different ore

characteristics and various industrial mineral processing operations for beneficiation.
