This salt does not contain any of the artificial additives or chemicals used in refined table salt. Murray River salt retains naturally occurring minerals and trace elements, such as magnesium and calcium, also lost in industrial processing. With decades of inland saline water mineral extraction experience, Murray River salt have developed unique techniques to sustainably extract salts from the inland brines. Murray River salt has been instrumental in contributing to efforts to combat the major environmental issue of salinity that exists in the Murray Darling Basin. Since operations began, tens of thousands of salt have been diverted from entering the Murray River, which is the major water source for food production in Victoria, New South Wales and South Australia. A nice choice of salt to buy to support Australian products and buying locally.
