Weir awarded £40 million sustainable tailings solution contracts

The brownfield expansion project will combine the thickened tailings streams from three major mines in the area: Ministro Hales, Chuquicamata, and Radomiro Tomic. The expansion is expected to have a total productive life of 20 years, and handle a slurry thickened to approximately 70% solid content – creating the opportunity to reuse process water and increasing the safety and stability of the storage facility.

The Weir solution includes a combination of GEHO® positive displacement pumps and WARMAN® centrifugal pumps to handle the large volume and high solid content of tailings from the three mines. With the full process enabled with NEXT intelligent digital solutions, the combined equipment will transport over 10 000 dry tph using less energy than other available solutions.

The initial £40 million contract awards will be booked in 2Q25. In total, the contracts represent the single largest order for Weir’s GEHO pumps, underlining the benefits of this technology for large scale, energy-efficient tailings transportation. We expect revenue to be recognised over the course of 4Q25 and early 2026 in line with project cut-off dates. After commissioning of the equipment, aftermarket support will be provided locally via Weir’s strong service centre presence in the region.
