Course Objective

Gravity concentration technology stands out as an indispensable method for the enrichment of chromium, iron, gold, coal and heavy mineral containing alluvial ores. In this course, the principles of gravity concentration and the factors affecting the efficiency of this method will be explained to the students. Different techniques of gravity concentration, effects of ore characteristics on the process and the major points in development of a gravity concentration process flowsheet will be discussed in details. Finally, the information about the mineral processing plants of Turkey employing gravity concentration methods will be delivered to the students.

Learning Outcomes of the Course Unit

1   To define the theoretical aspects of the gravity concentration process
2   To classify the gravity concentration techniques
3   To examine the principles of flowing film concentrators
4   To examine the principles of the concentrators achieving separation in a vertically moving water column.
5   To examine the principles of dense medium separators
6   To examine the principles of centrifugal separators
7   To examine the principles of the dry gravity concentrators
8   To construct the process flow-sheets for different ores
9   To assess a given gravity concentration flow-sheet
