| Summary |
|---|
| In this subject the students explained the principle of flotation, its importance in the treatment of minerals and waste, are familiar with chemical and physical Flotated the ongoing storyline, flotation reagents and their mechanisms of action, flotation devices and flotation methods of different types and raw materials. The theoretical basis for practical follow-up exercises in the lab, where students will apply the method of flotation on the specific samples of raw materials. |
| Learning Outcomes of the Course Unit |
|---|
| In this subject the students follow-up study explained the principle of flotation method of mineral processing and waste. Students in the laboratory exercises on the basis of experiments determined the ability of the flotation material and determine the optimum flotation conditions. |
