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.
