Therefore, the ore-bentonite slurries in the presence of Ca 2+ ions had reduced shear forces between particles, leading to improved settling rates and grinding performance. This is particularly true when the solid percentage of the bentonite-containing slurries was 62% or higher than that even at a lower bentonite concentration (i.e. 5%).
