(1992 and 2005)
In 1992, EBNER was awarded the contract for planning and delivery of a plant for the extraction of high-purity sodium sulfate (Na2SO4) from desert sand in the Middle East. This exists in the form of a salt layer with a thickness of approx. 100 mm on the earth’s crust. This salt layer consists mainly of inorganic salts such as sodium sulfate, sodium chloride, magnesium sulfate and calcium sulfate.
