Metso to deliver advanced flotation and dewatering equipment to Reko Diq copper-gold project
As part of the framework agreement announced in August 2024, Reko Diq Mining Company has awarded Metso the remaining major contracts for the supply of advanced Metso Plus beneficiation and dewatering equipment for its large-scale copper-gold project at Reko Diq in Pakistan.
Under the agreement, Metso will deliver a comprehensive suite of flotation and dewatering solutions. The total value of the newly signed contracts is approximately €70 million, with €40 million recorded in the Minerals segment’s order intake for the third quarter of 2025 and the remaining €30 million booked in the fourth quarter.
Metso’s scope of supply for the beneficiation circuit includes a state-of-the-art flotation flowsheet that combines TankCell® and Concorde Cell™ technologies. TankCell mechanical flotation cells will be used in the rougher and cleaner-scavenger stages, while the cleaner scalper and recleaner duties for ultrafine particles will be handled by high-intensity forced-air Concorde Cell units. This hybrid design maximizes metallurgical performance while maintaining operational efficiency.
According to Antti Rinne, Vice President of Flotation at Metso, TankCell technology continues to form the backbone of the rougher circuit, while the cleaner circuit is enhanced with Concorde Cell technology to achieve higher recovery rates at lower capital and operating costs. He notes that combining the two proven technologies offers a low-risk, high-reward solution ideally suited for low-grade, high-throughput flotation applications such as Reko Diq.
The Concorde Cell system will operate alongside the HIGmill™ regrinding mills that were ordered for the project in 2024. Together, they form one of the first fully integrated HIGmill–Concorde Cell circuits, delivering an energy-efficient regrinding and flotation flowsheet designed to improve recovery when processing finely disseminated and complex ores.
For concentrate filtration, Metso will supply four Larox® PF60 pressure filters along with auxiliary equipment and heavy-duty slurry pumps for both primary and secondary filtration stages. The package also includes five HRT High Rate Thickeners for various process duties, all equipped with Reactorwell™ technology to ensure high performance and process stability.
In addition, Metso will deliver a mill reline machine featuring award-winning safety enhancements and advanced Auto-Grapple™ functionality. This equipment will support maintenance operations for the large Premier™ ball mills previously ordered for the project. The order highlights Metso’s capability to provide grinding mills, mill linings, and reline machines as an integrated solution from a single supplier, ensuring compatibility, efficiency, and streamlined project execution.
