5 September 2016: CRC ORE and Whittle Consulting have published a study on enterprise optimisation using Grade Engineering strategies, which is now available for download.

Application of Enterprise Optimisation Considering Grade Engineering® Strategies

The Cooperative Research Centre for Optimising Resource Extraction (CRC ORE) and Whittle Consulting have recently collaborated to combine the principles of Grade Engineering® and Enterprise Optimisation concepts within an applied research framework.

The synergy between Grade Engineering principles and Enterprise Optimisation was assessed through a case study that examined potential Grade Engineering techniques using advanced modelling across the entire value chain, in a hypothetical, but realistic, mining operation.

With the publishing of this study, the collaborators are demonstrating the ability of Enterprise Optimisation approaches to evaluate and fully value the principles of Grade Engineering coarse-separation techniques. The case study examines potential responses for three coarse separation techniques across different domains in a hypothetical, but realistic, mineralised deposit underpinned by CRC ORE’s historical work with actual operations. The results from this work provides a basis for understanding the value of collaborations in Grade Engineering, strategic mine planning and operational optimisation, with the support of mining operations and projects.

Be guided through the process and judge the importance of the concepts to you.

The work documented in the report provides validation for the evaluation of Grade Engineering within an Enterprise Optimisation framework and supports the findings of previous Grade Engineering assessments performed by CRC ORE. The financial benefits of coarse separation responses used in the case study were found to be in line with business cases previously developed by CRC ORE in partnership with real-world mining operations and projects.

Grade Engineering®:
Grade Engineering® involves the use of coarse-separation techniques to remove lower-value or uneconomic material prior to energy, water and cost-intensive mineral processing activities. CRC ORE has performed technical proof-of-concept and economic evaluations for Grade Engineering in partnership with more than 20 mining operations and projects around the world. Central to these evaluations are the characterisation of coarse-separation responses within the deposit, identification of value adding strategies for operation and the development of a business case for Grade Engineering within existing and re-optimised strategic mine plans.

Whittle Consulting Pty Ltd:
Whittle Consulting provides a business optimisation service to the mining industry using a whole-of-business Enterprise Optimisation methodology that models a mining and minerals processing system from resource to market. Prober, Whittle Consulting’s proprietary Optimisation software, is used to produce a mathematically optimal schedule of material and financial movements through the operation. Of primary consideration is the effect of bottlenecks which control the rate of flow of money through the system. NPV is used as the financial objective as this accounts for the time-value-of-money and allows direct comparison of different cases. The Enterprise Optimisation approach allows determination of the full value from Grade Engineering, as Prober may alter the behaviour of all elements of the mining and mineral processing system to produce an optimal holistic solution.

  • 24 January 2018: CRC ORE has been involved in a number of high profile events in recent months. Read more about CRC ORE’s Annual Assembly line up and a successful site-based innovation leadership talk with Sumitomo at IMARC2017. CRC ORE also cooperated with METS Ignited to organise an initial consultation session for the consideration of a new CRC for the mining industry at IMARC. A couple of short courses were held – one on Geometallurgy in Tasmania and the respected Gold Plant Operators Course which was run in Kalgoorlie late last year.

    We are in the process of putting together the schedule for the coming year. Stay tuned for a listing of upcoming events in the next edition.

  • 5 April 2018: CRC ORE's Grade Engineering modelling programs have been strengthened over the summer thanks to the work of four motivated students who joined CRC ORE for our inaugural vacation intern program. Alex Perera, James Bamford, and Jacob Rogers joined us from The University of Queensland (UQ). Samantha Maslin joined us from the Queensland University of Technology (QUT) with the support of Austmine via its women in STEM (Science, Technology, Engineering and Maths) initiative. Hear more about their work by clicking on the video below.

  • 30 June 2017: Two of CRC ORE’s Board Members have been recognised for excellence in their chosen fields in recent months. Dr Sue Keay has just been named one of Australia’s first Superstars of science, technology, engineering and mathematics (STEM). This follows news that Joe Pease has been recognised in two prestigious mining industry awards. Also in recent months, CRC ORE was awarded a high commendation for an “exceptional paper demonstrating excellence” in the CEEC Medal 2017 round.
