Salinen Austria AG uses a method to extract the brine that involves sinking a borehole. A double-walled pipe is dropped into the vertical borehole and water under high pressure pumped in, dissolving the salt from the rock. The brine which this creates is then pumped back out and transported through an extensive pipeline system (built in 1595, the world’s oldest pipeline) to the saltworks in Ebensee am Traunsee.
At this point, the brine is cleaned and processed by means of thermocompression into ultra-pure vacuum salt with up to 99,9% NaCl content.
The vacuum salt has a wide range of applications: pharmaceutical salt, edible salt, industry salt for water softening, pool salt, animal salt, de-icing salt and much more.
Salt and Water
Brine has been removed from the mountain since the 12th century. In their efforts to produce salt, they took nature as their model: Just as the seawater evaporates due to the sun and wind to create sea salt, the salt workers heated up the brine until only pure salt remained. The fundamental principle has remained the same to this very day, though the methods and technologies have changed continually.
Today, it is possible to utilize almost 100% of the raw brine – the modern continuation of an over 400-year-old tradition of salt production in Ebensee in the Salzkammergut region.
