| Abstract: | In this article, different mill (ball, rod and autogenous) products of barite mineral were characterized in terms of their shape, roughness and wettability. 2D shape parameters were measured by the particle projections using SEM and expressed by elongation and roundness. Surface roughness values were determined and stated as the parameters of Ra value on the surface of the compressed discs. The wettability characteristics (ϒc) of barite were determined by microflotation and contact angle measurement techniques. Finally, some correlations were established between the shape parameters, surface roughness values and the wettability characteristics. In conclusion, the degree of hydrophobicity was favoured with elongation, while it was not favoured with roundness and roughness regardless of the type of the mill used. |
