ABSTRACT
The paper deals with an assay of flotation agent Montanol 800 and flotation agent on pyrolytic oil base P550 in the flotation of black coal from the locality of Darkov (Doubrava I reservoir), Czech Republic. Black coal flotation was tested in a closed circuit. At the same time, flotation concentrate frothing quality was observed, as it represents a significant problem during its dewatering in the operation conditions. With regard to the fact that coal preparation plants have a closed service water circuit, the residual concentrations of flotation agents have negative impacts on the flotation concentrate quality.
