Abstract
In this work, the contact angles of molybdenite powders in various size fractions (+150 μm, −150 + 75 μm, −53 + 38 μm, −38 + 20 μm, and −5 μm) were determined with the Washburn method by measuring the mass of capillary rise liquids in molybdenite powder beds as the function of time. It was shown that molybdenite powders had a smaller contact angle in superfine size range (−5 μm) than the common size range (+20 μm), which might be attributed to the large decrease of the face/edge ratio on molybdenite surfaces. Also, it has been found that the contact angle of molybdenite particles did not change as the decrease of particle size in the range of +20 μm.
