Newcrest Mining will trial advanced 4G Long-Term Evolution (LTE) and 5G mobile technologies underground at its Cadia mine, in New South Wales, Australia, to assess the potential of cellular delivery of data and video to support a smarter, safer and more sustainable mine, it says.

In partnership with Ericsson and Telstra Purple, Newcrest will deploy a private 4G LTE and 5G trial network in its underground operations at Cadia in the coming months. This announcement follows previous engagements where the trio worked to improve communications coverage, performance and safety with private 4G LTE at its Lihir mine in Papua New Guinea, and more recently for surface operations at the Cadia Valley Operations (CVO).

Speaking at the Sweden-Australia Sustainable Mining Summit in Sydney, Australia, today, CVO General Manager, Aaron Brannigan, said modern mining is a data-driven business, with technology and digitalisation creating new levels of productivity and safety, greater efficiency and reduced environmental impact.

“In the ongoing quest for productivity, efficiency and safety, Newcrest must use every tool at our disposal to boost performance at site while continuing to ensure that everyone at our mines gets home safely at the end of the day,” he said. “With 4G and 5G mobile technologies potentially offering better performance and capabilities than Wi-Fi, this trial will help Newcrest to assess its viability for greater coverage, capacity and functionality to support advanced underground automation, our Connected Worker strategy and future growth at Cadia.

“It’s an exciting time for Newcrest and for Australian mining, and this is a great practical example of how Australia’s biggest industry can leverage Australia’s position as a global 5G leader to further drive digitalisation in the mining sector and help develop a smart, safer and more sustainable mine.”

The trial will use Ericsson’s Private 5G (EP5G) solution for Industry 4.0 enterprises to assess different cellular approaches for coverage and capacity needs and deployment economics. It will include the use of various 4G and 5G radio types, massive- and multi-user MIMO (multiple-input-multiple-output) advanced antenna systems for high density and high capacity connectivity requirements, and Uplink Booster technology derived from custom-made Ericsson Silicon system-on-a-chip 5G processors to increase uplink signal strength and data throughput, Newcrest explained.

Ericsson’s Head of Australia and New Zealand, Emilio Romeo, said: “5G connectivity will be instrumental in enabling advanced teleremote and autonomous technologies, which are integral to industries such as mining. We’re delighted to be working with Newcrest and Telstra Purple to trial Ericsson’s 4G LTE and 5G solutions, and enable Newcrest to develop know-how on how to best deploy them underground.”

Telstra Purple Digital Transformation Executive, Paul Nicholls, said: “We’ve been thrilled to see what our 4G LTE and 5G mobile network technologies have been able to do through this project, from supporting wireless mining applications underground, to boosting safety for the local team. These technologies are absolutely transformative for a broad range of industries, and it’s exciting to be part of industry 4.0 innovation in Australia.”

Eriez HydroFloat technology to help improve recoveries at Newcrest’s Cadia operation

Eriez Flotation is to supply four HydroFloat® Separators to Newcrest Mining for use in Stage 2 of the miner’s Cadia Valley Operations (Cadia) expansion project in New South Wales, Australia.

This announcement follows the successful delivery, commissioning and ramp up of four Eriez CrossFlow Separators and two HydroFloats as part of the Cadia Coarse Particle Flotation demonstration plant in 2018.

Eriez Flotation Global Managing Director, Eric Wasmund, says: “When Stage 2 of the Cadia Expansion Project is complete, 100% of the Concentrator 1 tailings will be re-treated, significantly improving overall plant recovery for a coarser primary grind.”

The Stage 2 Cadia Expansion project primarily comprises the addition of a second coarse ore flotation circuit in Concentrator 1, using Eriez’s HydroFloat technology, and equipment upgrades in Concentrator 2, Newcrest said back in October. These changes are expected to see plant capacity go from 33 Mt/y to 35 Mt/y, while life of mine gold and copper recoveries could increase by 3.5% and 2.7%, respectively. Alongside this, the company was expecting a A$22/oz ($16/oz) drop in its all-in sustaining costs.

Newcrest is the first mining company to commercialise HydroFloat coarse particle flotation in sulphides and the first
in a tail scavenging application.

Wasmund added: “Eriez has been very fortunate to partner with Newcrest on coarse particle flotation. As partners we have learned many lessons together.”

Eriez-Australia Managing Director, James Cooke, noted: “During the commissioning of the demonstration plant, Eriez and Newcrest Mining worked closely together to perfect the technology. The decision was subsequently made to expand the application.”
