Scientists are working on a new range of materials characterisation analysers and techniques that could help unlock the value contained in Australia’s mineral deposits and improve processing performance, according to the October issue of Process.
Machine-mounted sensors, being developed through CSIRO Minerals Down Under Flagship, could help locate ore deposits, characterise the mining environment, and differentiate ore grades.
This will enable automated mining machines to respond ‘intelligently’ to the changing detail of the environment and offer real-time amendments to the mine plan.
Another prototype in development combines the best features of two existing materials characterisation techniques – x-ray diffraction and x-ray fluorescence – into a new slurry analyser.
The new prototype, dubbed XRDF for its dual origins, is capable of measuring both mineralogy and ultra-low elemental composition directly on a process-stream, without the need for labour-intensive, time-consuming and potentially error-prone sampling.
CSIRO scientist Dr James Tickner said the new prototype could offer a number of benefits over existing on-stream analysers.
“We’re not aware of any other system capable of doing accurate, on-stream mineralogy,” Dr Tickner said.
“The ability to detect elements at parts-per-billion levels in an on-stream system is unique.”“We’re not aware of any other system capable of doing accurate, on-stream mineralogy,”
Dr Tickner saidDr Tickner and his team are also working on gamma-activation analysis – a new analysis method that may deliver all the benefits of neutron activation without the need for a nuclear reactor.
The method is expected to provide accurate, multi-element analysis of mineral samples without extensive sample preparation, and measure very low levels of more than 30 elements in samples weighing just a few hundred grams.
The method could significantly improve sampling accuracy.

National Research Flagships
CSIRO initiated the National Research Flagships to provide science-based solutions in response to Australia’s major research challenges and opportunities. The 10 Flagships form multidisciplinary teams with industry and the research community to deliver impact and benefits for Australia.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
