An investigation of the effect of clay type on coal flotation along with DLVO theoretical analyses [PDF]
, 2020 Coals generally exist with clay minerals, which are very fine-sized minerals, and adversely affect the flotation of coal. For instance, they make the coal surface hydrophilic by coating coal surfaces and therefore, they inhibit bubble-particle attachment.
