Subject syllabus

1. Introduction. Carbon in nature, origin and chemical composition of coal.
2. Black coal deposits in the Czech Republic, brown coal deposits in the Czech Republic. Other fossil fuel deposits in the Czech Republic.
3. Classification of coal. Petrographic classification of coal. International Business Classification.
4. Sampling of coal. Definition and designation of basic coal components and their use in the coal treatment process. Physical properties of coal and their use in the coal treatment process.
5. Evaluation of coal editability. Utilization of coal editability diagram for selection of coal treatment technology.
6. Preparatory processes in coal treatment (picking, protection from foreign objects, sorting before treatment, blowdown). Basic types of used equipment.
7. Separation of coal (in suspensions, seedlings, HC, spirals, pneumatic separators, troughs, flotation). Special features of coal separation.
8. Auxiliary processes in coal treatment (product dewatering - separators, centrifuges, filters, reservoirs, sludge thickening - thickeners, drying).
9. Possibilities of control of coal separation efficiency and their practical utilization (T - curves, ash deviation, organic yield).
10. Water circulation in coal treatment plant (treatment, sedimentation of sludge, flocculation agents, closure of sludge circulation). Regeneration of suspension.
11. Waste management of coal preparation plants.
12. Basic technological schemes of hard coal treatment, their choice.
