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.

O STUDENT INTERNS JAN 2018

24 January 2018: CRC ORE has been fortunate to engage the services of four university undergraduates as part of the CRC ORE team for vacation internships. Alex Perera, James Bamford, Samantha Maslin and Jacob Rogers have joined CRC ORE over their university summer break, tasked with the further development of several of our Grade Engineering modelling programs. Alex, James and Jacob are currently completing their studies with The University of Queensland (UQ). Sam joins us from the Queensland University of Technology (QUT), with the support of Austmine via their women in STEM (Science, Technology, Engineering and Maths) initiative.

Each of the students was provided with a current status report across the programs they would be working on. They were also given a general overview of how we would like to improve the efficiency and capability of the targeted programs. With no pre-determined pathway of how to achieve the desired goal, the students have defined the issues and opportunities, broken up the work packages and re-combined the modules into improved programs that are contributing to meeting CRC ORE’s goals.

CRC ORE Student Alex Perera O

“I have been tasked with progressing CRC ORE’s project EvaluatORE, a modelling program to evaluate the opportunity for Grade Engineering. The program calculates the value each Grade Engineering lever delivers to an ore body and performs a preliminary ranking of Grade Engineering techniques for a mine site. Currently, data sets can be manually run through a simulation in Microsoft Excel, to calculate the value each Grade Engineering lever will add to the ore body. In the last couple of months, I have been working on improving the efficiency of this simulation. I’ve also been writing scripts within Excel to automate the process, enabling the application of the Excel simulation in future data sets. This will allow CRC ORE to quickly gauge the viability of Grade Engineering within an ore body, to decide if a more in-depth analysis is warranted.”

CRC ORE Student Sam Maslin

 

I’ve been working with the other student interns to improve upon existing tools and programs that are used in assessing the application of Grade Engineering to a mine site. I have mostly been involved with improving ForecastORE, a modelling tool which evaluates the economic benefit of different Grade Engineering strategies at mine sites. During my time here, I have enjoyed aiding in improving efficiency and run time of the program as well as implementing further functionality.”

CRC ORE Student Jacob Rogers

 

I’ve been focusing on improving the efficiency and functionality of ForecastORE by using Visual Basic to improve the underlying method of how results are calculated. I’ve also started looking through the literature for data sets comparing mineral grain size to material grade.

CRC ORE Student James Bamford

 

Since starting at CRC ORE, I have been progressing the ForecastORE project with Sam and Jacob. I’ve also just started working on a new project, DigORE, a modelling program which factors in the impact operational constraints have on the application of Grade Engineering. At the moment, it is assumed that in-situ heterogeneity is maintained after blasting has occurred and that any mixing of rock will not have a significant effect on the mining process. This project aims to be able to simulate the excavation of a synthetic muckpile after blasting, using a physics engine. The digging patterns are also to be taken into consideration so that the original block-model elements can be tracked.

With the success and initiative demonstrated by our interns this year, CRC ORE is looking forward to providing further industry experience to the next crop of undergraduates.

  • 24 January 2018: Bottlenecks, constraints, call them what you like. Every operation has to deal with the shifting nature of processing pain points as the orebody is progressively mined. Heterogeneity of ore can sometimes be blended to produce a consistent feed to a plant but more often than not operators need to deal with the variability in the feed’s metallurgical properties. So it’s important to know how big an issue the variability in the mine plan is for the processing production plan and in a recent Integrated Extraction Simulator (IES) project, that’s exactly what was investigated.

  • 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.
