The Gold Technology Group at Curtin University through the AMIRA P420 series of projects has recently developed the integrated liberation leach model ILLM for optimisation of gold plants. The model encompasses recovery by both gravity batch centrifugal concentrators or BCCs and leach adsorption CIPCIL circuits.
