By Mariager Fjord you’ll find the only place left in Denmark where we still obtain salt from the Danish underground. The salt factory Akzo Nobel in Dania produces approx. 600.000 tons of salt every year.
From underground to tabletop in 260 million years and a day
The factory obtains the mineral using a salt dome close to Hobro. The dome is a 2,8 miles wide and 3 miles deep, underground ‘salt pocket’ containing approx. 30 billion tons of salt, and it was created 260 million years ago.
The salt is collected from the dome by a drilling, where freshwater is pumped into the dome, resolving the salt. The salt solution is then transported to the factory in Dania through pump stations and a 16 miles long pipeline. In the factory in Dania, the salt undergoes a dehydration process, leaving the finest white salt - as we know and love it.
Fun with salt
A little teaser on the production of salt, but if you want to learn more, you should pay a visit to the Saltcenter in Mariager. Here you can visit an underground salt mine, bathe in salty baths, seethe your own salt and much more.
