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.
