Column flotation of bituminous coal

The objective of the paper was a comparison of classical and column flotation on samples of black-coal slurries from selected localities of okr and poland. Namely they are dukla mine, darkov mine, csm mine, csa mine, doubrava mine and kleofas mine. The acquired results imply that the methods of classical and column flotation are suitable for flotation of the slurries in question as all the tested black coal slurries from okr and poland are cokeable coals with a high flotation ability.
