VISCARIA RESTARTS ITS COPPER MINE with Jernbro as partner
As Viscaria prepares to reopen its copper mine outside Kiruna, extensive installations are required to pump out and treat the water that has filled the mine during its downtime. Jernbro is responsible for the piping and mechanical contracting in the new water treatment plant – a technically demanding assignment that is vital for the restart.

Installation and assembly, PrefabricationThe indispensable metal – and the partnership building the next phaseCopper is rarely seen. But without it, industry stops. Among other things, it carries electricity in our grids, powers machines in factories, and is a prerequisite for electrification. At the same time, supply is very limited – and demand is growing rapidly. It is in this context that Viscaria plays a crucial role.Read more

Welding, Svejsning, Svetsning, Turnaround og shutdown, VedligeholdelsePlant back in operationWhen energy must be produced, security of supply is essential – even when the boiler fails just before Christmas in Denmark. During periods of high load, there is no room for prolonged shutdowns, and a failure of key components can have a direct impact on both production and supply. This places demands on rapid mobilization, technical oversight, and safe execution from day one.Read more
