Rejecting mine waste can save billions

CRC ORE technology promises to revolutionise ore extraction and enable mining to become more profitable and environmentally sustainable. 

Globally, conventional mining methods are becoming less efficient and more expensive. Fewer high-grade ore pockets remain and they are increasingly difficult to access.

The Cooperative Research Centre for Optimising Resource Extraction (CRC ORE) aims to use innovation to improve value and reverse declining productivity in the mining industry.

CRC ORE’s Grade Engineering technology will help miners improve the recovery of valuable ore by identifying which separation process is most effective for the specific ore’s characteristics. Less energy and water will be used by rejecting most of the waste material at the beginning of the value chain, then only milling the higher-grade material to extract the desired mineral.

A full-scale production trial of Grade Engineering is currently underway at Minera San Cristóbal S.A. (MSC) in Bolivia — a major global producer of zinc, lead and silver.

The trial involves CRC ORE and its participants, mine owner Sumitomo Corporation, and equipment supplier Metso.

Dr Ben Adair, CRC ORE CEO says initial results of the trial are impressive. “So far, results show that by applying Grade Engineering to areas previously designated as ‘mineralised waste’, the feed grade to the mill can be increased more than 2.5 times,” he says, adding that waste material can potentially be converted into high-grade ore feed.

“In this case, the big benefit of Grade Engineering is its potential ability to extend the life of the mine and add up to $1 billion to its value,” says Dave King, MSC operations director.

Australian mine operators are keenly watching the trial and CRC ORE is currently working with Australian participants to secure equivalent trials at their production sites.

  • 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.

  • 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. Hear more about their work by clicking on the video below.
