China and Australia are the world’s two largest producers of gold. So, it’s fitting that a device combining Australian and Chinese research, and capabilities in high-tech manufacturing, is set to shake up the industry.
Ore processors need to know how much gold is in their raw material to get the most out of it. The current industry standard for testing ore is the fire assay, an elaborate and time-consuming process that requires temperatures over 1000 degrees and toxic chemicals such as lead. It also takes at least 8 hours to complete.

American mines are safer and more efficient thanks to Australian technologies
‘Blood tests’ for big machines
Mining companies across America are increasing the reliability of their trucks, diggers, and other big machines, and saving hundreds of millions of dollars in the process.
They’re giving these big machines regular health tests and comparing the results with a global database for that machine.
The result? They’re fixing machines before they break. This preventative health system was developed by an Australian company, Dingo, which now has 40 people working at its bases in Denver, Brisbane, and Calgary.

Statisticians have revealed the surprising source of dust that plagues townships beside a Hunter Valley rail line delivering coal to Newcastle’s busy port.
Airborne dust increases as trains pass. But it wasn’t clear exactly how—for example, whether the dust was escaping uncovered coal wagons or coming from the diesel engines pulling the wagons. The answer was surprising.
Mathematicians from the ARC Centre of Excellence for Mathematical and Statistical Frontiers correlated air-pollution data against information on passing trains and weather conditions.
