The gravity separation based on the density was used to remove the organic carbon from the coal-series kaolin. The results indicated that the loss on ignition of decarbonized kaolin was decreased by 44.22%, and the contents of Fe 2 O 3 and TiO 2 were also decreased by 48.57% and 59.57%, respectively ( Peng et al., 2017 ).

The settling rate for quartz tailings exceeded 30 m/h, and the settling rate for quartz/kaolin tailings in a 60/40 ratio was only 5 m/h. These low settling rates were due to the smaller size of the aggregates in the presence of the kaolin particles, due to the fine size of the clay particles and their plate-like shape with a high specific ...
