Jing and her team are already using their data insights work to deliver productivity and commercial gains to businesses across Rio Tinto.
Jing was involved in a small cross-functional team that developed a system to optimise plant and truck utilisation at Iron Ore's Hope Downs 1 mine in Western Australia in just two weeks.
The team rose to the challenge of automating elements of the interface between the ore crusher and haul truck. They created a system that analyses real-time data captured at the crusher, such as bin levels and run-rate, and overlaid real-time truck data such as location and payload.
As a result, the crusher can "speak" to the trucks and let them know when it needs material or, alternatively, when the truck can be re-directed to the stockpile. It means the equipment can always be utilised at an optimum level, helping to extend its life, minimise downtime, and reduce energy and other operating costs.
The work has the potential to increase material through crushers at all manned sites in the Pilbara by more than 1 million tonnes a year, not to mention the potential in other product groups.
"The challenge was to create a working prototype that would be able to operate sustainably at Hope Downs 1 with the view to rapidly replicate across all Pilbara mine sites," said Michelle Radley, manager, Technology Integration, Studies & Technology, Iron Ore.
"The team successfully achieved their aim, which was a great result given the time available.
"The prototype showed the ability for the crusher to call for trucks, which will lead to an increase in production throughput.
"Since the sprint work, we have worked with Modular, a mining software company, to develop a sustainable solution. This is now in place and operating well at Hope Downs 1 and we are in the process of rolling it out to all of the other manned sites in the Pilbara."
Jing also led a team of interns from a local university in Singapore to help optimise bunkering activities for Rio Tinto Marine and Rio Tinto Procurement. For their work, the team received one of the company's "Ground breaker" employee recognition awards from chief executive J-S Jacques.
Currently she's working with the Aluminium and Information Services & Technology groups to optimise pricing by analysing smelter data and with the Copper & Diamonds and Commercial Excellence teams to ensure Rio Tinto gets the best prices for copper concentrate.
Jing says tangible data-driven solutions like these inspire her to come to work every day.
"I know with certainty that what I do each day is contributing to the improvement of the businesses, be it in productivity or commercially or for other support functions in the Group," she said.
