— Most research on the separation mechanism of a KC has been conducted with MD3 concentrators and synthetic ores. KC-MD3 with a 3-in. (7.5 cm) concentrating cone is suitable for laboratory research because it is portable and convenient, and the amount of raw material is adjustable (Banisi, 1992, Putz, 1994).Synthetic ores …

— It should be noted that the density of bentonite (2.3 g/cm 3) and kaolin (2.65 g/cm 3) are very similar as the density of quartz (2.7 g/cm 3); however, bentonite and kaolin particles are very fine (80% passing 10 µm) and thus were transported to the tailings due to the high drag force relative to the centrifugal force.
