ABB tailings dam electrification at Aitik: integration lessons for engineers

30 Second Briefing
ABB has expanded electrification and automation at Boliden’s Aitik tailings facility, integrating power distribution, process control and monitoring to support safe capacity growth at Sweden’s largest open-pit copper mine. The upgraded system strengthens water storage and recycling, with automated instrumentation and real-time data improving surveillance of dam performance and water balances. For geotechnical and tailings engineers, the project signals tighter coupling of electrical infrastructure, SCADA and dam monitoring as facilities scale to handle higher throughputs under rising copper demand.
Technical Brief
- ABB’s solution integrates tailings dam power distribution with process control into a single coordinated system.
- Electrification upgrades include new substations and switchgear dedicated to the tailings and water circuits.
- Automation extends to pumps, valves and decant systems, enabling remote operation and interlocked safety sequences.
- Instrumentation feeds real-time levels, flows and power status into a unified SCADA for operator oversight.
- Remote operation capability reduces personnel exposure on dam crests and around high-energy electrical equipment.
- Integration of water management and electrical systems supports more conservative freeboard and discharge control strategies.
- Similar large-scale tailings facilities can use comparable electrification–automation coupling to formalise engineered safety barriers.
Our Take
ABB’s tailings dam electrification and automation work at Boliden’s Aitik copper mine in Sweden lines up with its recent push into critical infrastructure power systems, such as the full electrical package for Vulcan Energy’s Lionheart geothermal lithium project in Germany, signalling a strategy to own the ‘backbone’ of complex process sites in Europe.
Boliden’s Aitik deployment dovetails with the company’s separate move to roll out ‘green fleets’ across its European copper, nickel and zinc operations, suggesting that electrified, automated tailings management will be assessed alongside mobile fleet decarbonisation as part of its overall emissions and safety risk profile.
In our database of 371 mining stories, copper pieces tagged to Europe like Aitik increasingly sit at the intersection of ‘Projects’ and ‘Safety’, indicating that for mature copper districts the differentiator is less new orebody discovery and more how operators harden existing assets such as tailings storage through automation and power system upgrades.
