Team ARNUT wins Inaugural Hunter Valley Hackathon
Over the weekend of 26th – 28th August the inaugural Hunter Valley Hackathon was held in Newcastle. Hackathon events are run by Unearthed, with this program starting in 2015 with 5 events nationwide, with the basic premise being to solve industry defined challenges over a 54 hour time period. This year, this successful program has been expanded and even includes three international locations. The focus of Unearthed can be described as “Accelerating innovation in the resources sector”. Our team (“ARNUT”), comprised of Dr Wei Chen, Dr Tim Donohue and Mr Jeremy Miller from TUNRA Bulk Solids, took on arguably the most difficult of the 3 challenges. Our challenge was to “Automate image analysis of Hylogger drill core data”, and after an intense weekend of development, we were very proud to be awarded first prize.
Our prototype is able to cross-correlate three-band RGB high resolution drill core images with hyperspectral line scanning, resulting a visual mineral mapping directly overlaying on top of the drill core image. The motivation for this work is to lead to more accurate, accelerated and efficient mineral mapping for large mineral deposit exploration, which has the potential to significantly increase the return of investment for the A$600 million exploration cost annually in Australia.
The event itself was really well run, and was both fun and challenging to be involved with. The mentorship provided with regard to the challenge and interpretation of data was outstanding, and the assistance and advice provided by the Unearthed team was excellent. The event is really a great place to test your skills, and we would encourage anyone else considering entering in the future to have a go!

TUNRA Bulk Solids seals partnership with Brazil #1 University
The University of Newcastle through TUNRA Bulk Solids has signed an MoU with USP (University of São Paulo), the Number 1 ranked University in Brazil (Times Higher Education World Universities Ranking 2016). This MoU will enable collaboration on specific areas especially focused on the mining, minerals processing and materials handling field and will be managed by Dr. Ken Williams, TUNRA’s General Manager-Research.
This relationship started early in TUNRA Bulk Solids’ presence in Brazil, in 2014, when TBS’ General Manager, Dr. Tobias Krull, visited Brazil to participate as a keynote speaker in the ABM symposium (Brazilian Association of Metallurgy, Materials and Mining) and met Prof. Arthur Pinto Chaves, one of the key names for Materials Handling in the Brazilian industry. Being a retired professor in USP, Prof. Arthur passed on the management of this agreement to Prof. Ana Carolina Chieregati, who specializes in sampling of bulk solids and is now responsible for the MoU.
In 2015, TUNRA Bulk Solids and USP organized the first Bulk Solids Handling Workshop, which gathered approximately 60 people from the mining, steel and grains industry for over 20 presentations on bulk solids handling related topics, including international speakers from Australia, Chile and Italy. The event, which had the presence of TUNRA Bulk Solids’ Engineering Manager, Dr. Tim Donohue, proved to be a success and both parties are looking forward to other initiatives, which may include courses and joint research projects.

TUNRA Bulk Solids’ was recently visited by the Hon. Anthony Roberts MP, NSW Minister for Industry, Resources and Energy along with Parliamentary Secretary for the Hunter Scot MacDonald MLC. The visit was part of a wider tour of the Newcastle Institute for Energy and Resources (NIER) Precinct and the University of Newcastle. During his time visiting the laboratory of TUNRA, Minister Roberts spent time discussing two innovative projects that are being driven through engagement with Industry;
(left – right) Dr Alan Broadfoot (NIER Director), Mr Scot MacDonald (Parliamentary Secretary for the Hunter), Hon. Anthony Roberts (NSW Minister for Industry, Resources and Energy) and Dr Ken Williams discussing the effectiveness of the large impact wear tester (shown in the background)
Dr Ken Williams spent time discussing a new innovative test rig that is able to quantify impact wear in wall liners. The information measured with this test rig can be applied to the mining, mineral processing, agriculture, energy and process industries. The assessment and selection of effective wear resistant materials is central equipment life when handling particulate materials associated with these industries. As such, TBS have designed, built and operated innovative wear assessment equipment for use by industry to accurately assess wear liner effectiveness. When you consider that a simple transfer chute may take 1-2 days to reline with new wear liners, at modern tonnage rates of 5000 to 10000 tonnes per hour, the financial gains derived from the life cycle improvements and maintenance planning derived from these tests are obviously substantial.

Dr Tim Donohue spent time discussing a 1/5th scale model of a Train Load-Out. The motivation behind this scale model, which has been developed through a collaborative research partnership with Schenck Process, is to develop a real time weigh system to track the mass of product loaded into each rail wagon as it is being loaded. This new technology offers opportunities to maximise the mass in each wagon while not exceeding weight limits and represents a step change, as current systems can only weigh the loaded wagons downstream with no opportunity for mass optimisation.
