Gold Processing
Project No. :P420F Status :Management
Commenced : 01 Jun 2016 AMIRA : Mr John Visser
Value : AUD $3,658,500.00 Duration : 3 years

The AMIRA Gold Processing Technology project has delivered industry focused research outcomes for 28 years. The current project has five themes: Theme 1: Enabling process optimisation on existing operations: This theme supports operations by facilitating technology transfer through the use of courses and workshops using software developed in the AMIRA P420 projects and implementing it for plant optimisation. Theme 2: Optimising post-crush liberation for pre-concentration: This theme is focussed on reducing the processing costs associated with low grade ores, either through optimal pre-concentration (coarse particle gangue rejection), or through optimised heap leaching. Theme 3: Optimising reagents and consumables in terms of type, utilisation and management: This theme explores the potential of new or optimised conventional reagents and consumables to lower overall processing costs or yield higher recoveries, whilst reducing the overall environmental and occupational health and safety risks. Theme 4: Managing the water balance and the chemistry of tailings, raw and recycled water: This theme seeks to address one of the decreasing availability of water of suitable quality amidst ever increasing climatic and societal pressures. Theme 5: Enhancing the processing of difficult ores (polymetallic, preg-robbing, high clay, high sulfide ores): This theme deals with difficult ores, be they polymetallic, refractory and/or preg-robbing. The research organisation for this project is Curtin University, Australia
