pH levels and mixing rates, a significant boost in water
recovery is observed with increasing flocculant dosage. This
finding is supported by a previous study conducted in the
dewatering of iron ore fine tailings. (Yang et al., 2019) In
such operational scenarios, water recoveries consistently
exceed 83% when doses exceed 80 g/tds and mixing rates
rise above 100 rpm. This finding underscores the pivotal
role of precise dosing and controlled mixing parameters in
achieving optimal water recovery rates, offering valuable
insights for rationalizing tailings management strategies.
The considerable curvature in each contour plot in
Figure 6 (a", b", c") indicates significant interaction effects
on water turbidity (WT) among the studied factors. pH
emerges as the primary factor influencing supernatant tur-
bidity, with very high or very low pH values resulting in
the highest turbidity. The optimal pH values fall within
Figure 6. Response contour plots showing the effect of three factors on ISR, WR and WT uncoded values: ISR: (a) pH-FD (b)
