Sodium chloride is extracted from various sources such as rock salt, solution mining, sea salt, etc.
In rock salt, the solid salt is extracted manually from underground deposits, while in solution mining, water is injected into the underground salt
deposits, creating brine, which is then evaporated.
In solar evaporation, solar energy is used to evaporate water from sea salt, leaving behind salt crystals.
Worldwide 30’000t/h salt is produced with Ferrum centrifuges.
Below is a general description of the solution mining method, whereby the centrifuge plays an important role in the processing:

Identifying and addressing processing challenges – such as consistent residual moisture levels, minimizing crystal breakage, and achieving optimal purity – is at the forefront of our operations. Ferrum’s comprehensive approach significantly reduces operational costs and boosts efficiency.
