increases towards the right and as time decreases towards the
left, there is a slight reduction in praseodymium recovery
even at relatively low intensity. Figure 10e is the one factor
plot for the main effect of mixing intensity on the recovery
of neodymium. It is shown in the graph that decrease in
intensity resulted in the increase of neodymium. Recovery,
while an increase in the mixing intensity yielded lower neo-
dymium recovery. Lastly, Figure 10f depicts the one factor
plot for the main effect of biochar mass on the recovery of
dysprosium. As observed in the figure, low biochar mass
resulted in low recovery, while an increase in biochar mass
to the right side of the graph resulted in higher level of
recovery for dysprosium.
Comparison Between RVM and Stirring Using
Synthetic Solution and REEs Ore Leachates
Figures 11 presents the comparison between resonant
vibratory mixing and stirring as intensification methods
for the recovery of the REEs selected for this research.
It is interesting to observe that RVM performed better
than conventional intensification (stirring) in enhanc-
ing higher uptakes of REEs from solutions. As shown in
Figures 11a–11c that while the two intensification methods
