Coal Preparation

Students will be introduced with the industrial processes of coal preparation and refining in the aim of coal valorization and obtaining quality products of clean coal, as well as other clean coal products, suitable for further industrial use and processing. Students will be introduced with the parameters for the evaluation of the selection of the processes and also, with the control of the coal cleaning process and the way in which this control is achieved in industrial conditions.

Students will be able to solve practical tasks in the field of coal preparation and also, to actively introduce in the work of industrial plants for the preparation and refining of coal, scientific research work or to continue studies in this field.
