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.
