Gekko Systems continues support for the AMIRA P420 project

Supplier News
Gekko Systems  has been continuously sponsoring the AMIRA P420 project since its inception 15 years ago, underlining its commitment to the mining industry.

Now into its fifth project (P420E), the P420 project has made significant contribution to the understanding of many gold recovery processes, developing a range of tools to support metallurgical process engineers as they understand, optimise, manage, retrofit and design their plants.

The P420E project will continue developments in cyanide based gold recovery processes, including processes for high copper gold ores and silver gold ores, and with a renewed emphasis on refractory gold deposits. New environmentally benign lixiviant systems for low-grade ores, evaluated for simulated in-situ and heap/dump test environments will be explored under the ‘Future ores’ section.

The Gold Technology Group within Curtin University will perform the bulk of the Research, Development and Technology Transfer with internal collaboration within Curtin University, and external collaboration with the CSIRO as required (AMIRA P420E proposal document, 2012). 

The continuous gravity model was developed as part of the P420 project by the Gold Technology Group, working in-conjunction with the previously known Cape Technikon (currently incorporated into the Cape Peninsula University of Technology).

The Parker Centre Gravity Model (PCGM) was developed during the P420B project in order to facilitate the optimisation of gravity gold recovery circuits. A Continuous Recovery Simulation Model (CRSM) is available to simulate the recovery of sulphide minerals by continuous recovery devices and processes, such as jigs and flash flotation.

According to Jacques Eksteen, project manager for P420E, the continuous gravity model developed during the collaborative P420 research project represents a critical step forward for gold producers to reduce downstream costs and potentially improve overall process efficiencies.

Mr Eksteen adds that Gekko’s support in the P420 project has been an important link in the partnership between technology suppliers, research institutions and gold processing operations, through provision of gravity recovery technology, process models and ore characterisation procedures, and test sites for model and technology evaluation.
