length of the electrode-grizzly bars. The results of the elec-
tric field simulation are presented in Figure 4. This uniform
distribution of the electric field extends along the entire
length of the electrodes. Consequently, each particle within
the processing zone is given an equal opportunity to be
selectively targeted by the discharge process. This has been
confirmed in practice by testing synthetic particles made of
grout in the novel system.
The JKMRC novel HVP electrode-grizzly concept is
a significant advance towards the implementation of the
technology for mineral processing. This new HVP system
is applicable to many other commodities, including other
critical minerals required for the impending global energy
transition.
A significant amount of work has been undertaken to
characterize and demonstrate the electrode-grizzly concept
(André et al. 2022 Lay et al. 2023). A portion of the work
