Abstract
The distribution of hydrophilic/hydrophobic sites on coal is one of the essential factors in a column flotation process. In this study, methylene blue adsorption on coal was conducted to estimate the area of hydrophilic surface. The experimental results successfully suggested that methylene blue was adsorbed on the hydrophilic surface sites on minerals and oxygen-containing functional groups.
