    Metso OKTOP Cooling Tower: retrofit and shutdown benefits for process engineers

    Metso OKTOP Cooling Tower: retrofit and shutdown benefits for process engineers

    First reported on International Mining – News

    30 Second Briefing

    Metso is launching its third-generation OKTOP® Cooling Tower for demanding slurry and electrolyte cooling duties in metals refining, combining existing OKTOP process technology with a more compact footprint aimed at constrained brownfield plants. The unit is engineered for rapid installation and simplified maintenance, targeting reduced shutdown durations and easier access to internals compared with conventional large cooling towers. For process engineers, the compact design offers retrofit options where space limits have previously constrained debottlenecking of heat removal capacity.

    Technical Brief

    • Third-generation OKTOP® Cooling Tower is configured specifically for slurry and electrolyte cooling in metals refining.

    Our Take

    Metso appears in relatively few of the 290 tag-matched Projects/Product items, so another proprietary unit like the OKTOP Cooling Tower signals the company is leaning further into supplying modular process islands rather than only large, bespoke plant packages.

    For brownfield concentrator upgrades, compact cooling units such as the OKTOP-branded equipment typically matter most where operators are trying to debottleneck heat-sensitive stages (e.g. solvent extraction or crystallisation) without expanding building footprints or adding new structures subject to permitting.

    In our database of Mining category stories, most plant-equipment launches focus on comminution or filtration, so a cooling tower product suggests Metso is targeting the less crowded niche of thermal and process-control infrastructure, which can be a lever for incremental throughput gains at existing sites.

    Suncor Cat AHS at Mildred Lake and Komatsu Mud Mode: integration notes for mine planners

    Suncor has commissioned its first Autonomous Operating Zone at Syncrude’s Mildred Lake oil sands mine, extending its autonomous haulage system deployment beyond the existing fleet of about 140 autonomous trucks already running at other Suncor sites. The new zone uses Cat AHS fleets under Suncor control (since late 2021) and is complemented by Komatsu AHS trucks at Base Plant operating with a dedicated “Mud Mode” to maintain traction and control in soft ground. For mine planners, this signals wider-scale AHS integration across multiple pits and variable ground conditions.

    Central Nevada Gold’s Mule Canyon acquisition: project and risk lens for engineers

    Central Nevada Gold has completed a US$20 million acquisition of Newmont’s past‑producing Mule Canyon mine in Nevada, targeting a prefeasibility study and key permits in H2 2027 ahead of a potential 2028 construction decision. Mule Canyon previously produced about 500,000 oz gold at an average head grade of 3.8 g/t with ~94% metallurgical recovery, and comes with a database of 2,149 drill holes totalling over 335,000 metres across six mineralised zones over 2.5 km. The company plans an IPO as early as 2027 after a 20‑hole metallurgical and infill drilling programme to upgrade inferred resources and de‑risk the project.

    Greenland Mines’ Sarfartoq licence: key project and offtake notes for mine planners

    Greenland Mines has secured government approval under the Greenland Mineral Activities Act for the indirect transfer of the Sarfartoq carbonatite complex exploration licence, clearing a key condition in its US$35 million acquisition from Neo Performance Materials, which retains offtake rights to up to 60% of future ore or concentrate. The Nd-Pr-enriched project, about 60 km from Kangerlussuaq, carries a historic NI 43-101 resource with 5.88 Mt indicated at 1.77% TREO and 2.46 Mt inferred at 1.59% TREO, based on 23,000 m of drilling. The news sent Greenland Mines’ NASDAQ-listed shares up more than 22%, giving the company a market capitalisation of US$31.4 million.
