Flotation behaviour of weathered coal in mechanical
网页2013年9月1日The flotation of fine low rank or oxidized coal is difficult to achieve with the common coal flotation collectors like kerosene, fuel oil or diesel oil (oily collector). The amount of adhesion of oil droplets onto low rank coals is very small and the use of oil alone does not improve flotation [8].
