Mine tailings (MTs) were obtained from a gold mine located in Shandong province, China. Laser particle size analysis in Fig. 1 (a) indicates that the characteristic particle sizes of MTs are d 10 = 3.34 μm, d 50 = 11.15 μm, and d 90 = 37.97 μm. In China, the nonferrous and gold mines classify the mine tailings with an average particle size of less than 0.019 mm as ultrafine tailings.
