Metso to deliver key crushing and grinding technology to the Hemi Gold Project in Australia

Metso Premier ball mill

Australian mining company De Grey Mining Limited has awarded Metso orders for a Superior™ MKIII 50-65 primary gyratory crusher and two 14MW Premierball mills. The equipment will be installed at De Grey Mining’s Hemi Gold Project located in the Pilbara region of Western Australia. The combined order value of over EUR 20 million is booked in the Minerals segment’s first-quarter 2024 orders received.

“Our aim with the Hemi Gold Project is to deliver a Tier 1 gold project and make a future top 5 Australian Gold Mine from a production perspective. The 10+ Mtpa process circuit will be equipped with state-of-the-art equipment and proven technologies contributing to responsible ore processing. We’ve just partnered with Metso in delivering the first key items for the process circuit, namely the primary gyratory and ball mills, and we’re looking to make the rest of the process equipment decisions soon. De Grey will make a series of payments according to milestones achieved over the manufacturing period and final commissioning, typical for contracts of this nature, commencing in March 2024,” says Glenn Jardine, Managing Director of De Grey Mining.

“Metso’s third generation SuperiorMKIII primary gyratory crusher, renowned for its safe and efficient operation, will be the driving force for Hemi Gold’s entire processing circuit, and the two Premierball mills will provide optimized grinding performance and the highest availability for the concentrator. Both mills are equipped with failsafe Metso Polymer Hydrostatic Shoe Bearing (HSB) systems, significantly increasing reliability and reducing maintenance costs,” says Kai Rönnberg, Vice President, Minerals, Asia Pacific at Metso.

“We look forward to working on this project and future ones with De Grey Mining. In terms of servicing our customers when plants are operational, Metso also has an extensive footprint in Australia. Our state-of-the-art Karratha Service Centre in the Pilbara, which will be Metso’s largest Service Centre globally, opens this March. The Karratha Service Centre will be able to support our customers, as well as the Hemi plant, with the latest technologies and sustainable aftermarket solutions,” concludes Rönnberg.
