the IsaMill ™ to increase mineral reactivity and eliminate
the potential for passivation of the mineral surface during
leaching. This enables leaching to occur at atmospheric
pressure. Oxidative leaching of the finely ground concen-
trate occurs in the OxiLeach ™ Reactor System. The aspect
ratio of the tanks coupled with supersonic oxygen injec-
tion via the HyperSparge ™ system maximises oxygen mass
transfer and utilisation by creating a hydrostatic head, high
shear, and increased particle contact.
Figure 4 summarises the potential stages of testwork,
design and commissioning that might apply to extend the
life of a depleting asset through the addition of processing
solutions to treat the sulfide component of an ore body.
