NextOre introduces MR analyser for underground copper mines

NextOre has announced the availability of its new Magnetic Resonance (MR) analyser, specifically designed for underground copper mining operations.

The company's CEO, Chris Beal, highlighted the need for efficient and cost-effective solutions in the mining sector.

"In the current economic climate, with traditional large-scale capital expansion projects becoming less viable, operators are looking for smarter, lower-risk solutions that deliver immediate value," Beal commented.

He further explained, "Our latest MR analyser provides a powerful, real-time tool that enables underground mines to optimise ore movement, reduce waste, and improve overall productivity without the need for costly infrastructure upgrades."

The OG3 sensor, derived from CSIRO's initial design, is specifically configured to handle the demands of underground haul trucks.

This adaptation includes enhancements such as ruggedisation to withstand harsh environments and improved efficiency in crane positioning.

The sensor can analyse up to 50 tonnes of material in under a minute, offering real-time data for mining operations. "Our goal has been to ensure that the sensor is easy to install, simple to operate, and provides fast, actionable insights," Beal said.

He also noted that "the higher the grade of the material, the shorter the analysis time. Conversely, lower-grade material requires slightly longer scanning durations."

The operational implications of NextOre's analyser are significant. It allows for real-time ore grade measurement, which aids in reducing unnecessary haulage by rejecting low-grade material at the source.

Additionally, it improves ore blending, enhances downstream processing efficiency, and optimises material movement from satellite orebodies to central processing plants. The development thus contributes to overall productivity while reducing operational costs and environmental impact.

NextOre has already established a global presence with the successful installation of MR analysers in operations such as First Quantum Minerals' Kansanshi copper mine in Zambia and a large-scale conveyor application in Chile.

The first deployment of the OG3 sensor in an underground setting is anticipated in New South Wales in 2025. Initially, the unit will be used with 30-50 tonne mine trucks, with the prospect of extending its use to Load-Haul-Dump (LHD) bucket loads, further improving underground mining efficiency.
