The Integrated Extraction Simulator (IES) has been developed from the combined research of Cooperative Research Centre for Optimising Ore Extraction (CRC ORE), The Julius Kruttschnitt Mineral Research Centre (JKMRC) and AMIRA to integrate and optimize drill & blast, crushing, grinding and flotation. Providing mine management with a cloud-based decision support platform that enables all production departments to coordinate and optimize as one team.
Metallurgical Breakthroughs – new thinking in mining and metallurgical modelling
Integrated Mining Value Chain
IES is the first platform to integrate all mining and mineral processing operations into one contiguous flowsheet environment, starting with drill and blast and stepping through each stage of haul, stockpile, blend and mix prior to crushing, grinding and flotation.
For the first time mining and mineral processing engineers can model the impact of every operation in the flowsheet on overall productivity. IES provides immediate response: change the blast design and seconds later see the impact on grinding throughput in the mill and concentrate recovery in the flotation plant.
Multi-Component Material Processing: Capture, Consolidate, Balance, Calibrate, Optimize
Mining operations have to process multiple material types simultaneously in their operations – so their simulator platform should be able to as well. IES has been designed from the ground up as a platform for multi-component modeling and the new generation equipment models are responding to the challenge. Trusted models from years of research have been upgraded to “multi-component” capability and IES offers model developer’s sophisticated tools to facilitate multi-component processing.
New Performance Metrics: Economic and Environmental
Users can define expressions that calculate operating cost, power consumption, water usage and even CO2 emissions for each piece of equipment as well as the whole flowsheet. The optimization function can be used to establish production targets that meet environmental and cost constraints.
Mill Performance Management
Mill Performance Management (MPM) is a new module of IES that has all the functionality required to capture and process mill surveys in detail from the first stream sample to full flowsheet optimization.
With MPM the mill survey team can capture field observations, consolidate observations and laboratory assays into normalized flows and mass balance individual operations or subsets through to the entire flowsheet.
Once the flowsheet has been balanced MPM facilitates calibration (model fitting) and automatically creates a new flowsheet with the calibrated equipment models.
The calibrated flowsheet can then be used to optimize the operator settings and flows of the mill to get improved operational performance.
Software Breakthroughs – better technology for improved productivity.
IES is deployed as a cloud-based subscription service where all the user needs is a browser and internet access to start building flowsheets. IES uses Amazon Web Services to provide safe, secure infrastructure with continuous backup and industrial grade data security. The design of IES allows the user to “scale up” and select the level of computing power to apply to mass simulation challenges.
Stand-alone deployment is available for times when where internet access is limited or users with sensitive data require independent implementations.
Mass Simulation Capacity
Users can initiate multiple automated simulations from CSV files containing multiple flowsheet model parameters and material properties. The data in each row of the CSV file is mapped to the simulation engine and triggers a simulation.
Process entire geomet-enabled block models or mining extraction sequences in order to understand recovery and spot bottlenecks in long term mine plans. IES will map simulation results such as throughput and recovery back into the block model for use in downstream processes such as ultimate pit and optimized mine planning.
Mass Simulation can also be used for setting up sensitivity analysis where multiple parameter ranges are tested against controls to understand performance relationships.
Simulation Results Database
IES stores a record of each simulation performed on every flowsheet for future retrieval, modification and comparison. The database can be exported to Excel for further analysis and interpretation, including graphical representation for reporting.
Each simulation record contains sufficient data to completely rebuild the graphical flowsheet and all of its input parameters and material properties. The user is in complete control of the flowsheet development process and can easily go back and retrieve old flowsheets in order to create alternative processing options.
Model Prototyping and Development
IES provides a model-scripting environment that allows mine operators and consultants to modify the standard models to suit site conditions as well as prototype completely new equipment models from scratch.
The user simply drags a special “BlackBox” model icon onto the flowsheet, opens it up and scripts a new piece of equipment with all of the facilities of sophisticated multi-component processing. The BlackBox can then be used together with tried and trusted industry standard models to get the best of both worlds – world’s leading technology modified to local conditions.
IES provides users with a platform to publish new models so other users can access their work or alternatively the user can choose to keep the model private.
