A method of producing solar salt including putting dried solar salt into a color sorter to selectively remove foreign substances. The dried solar salt may be obtained by removing bittern from raw solar salt collected from a salt pond to obtain bittern-removed solar salt washing the bittern-removed solar salt with concentrated brine to remove foreign substances naturally dehydrating the washed solar salt to a water content of about 12 w/w % to about 17 w/w % by storing the same in a ton bag having a mesh bottom, to obtain dehydrated solar salt and drying the dehydrated solar salt by heating. Solar salt, which is hygienically clean and is rich in mineral components, may be conveniently produced.
