The flolation tests of anthracite and bituminous coal with xanthate or oily collectors were made. The flotation recovery increased with the amount of xanthate added, which was evidently taken up upon the surface of the coal. When the coal was degassed in vacua or immersed in water in order to remove the adsorbed gas, the floatability and the amount of xanthate were reduced to the extent greater than that for untreated coal. They were restored to the former state by drying, following the above treatment. Consequently, it is considered that the action of xanthate-type collectors is effective with the adsorbed gas phase on coal surfaces.
