it's very simple
during the process of evaporation there is precipitation of NACL only and the rest go back to the sea as brine - the NACL is pure and clean with micro elements but without the macro elements that you add seperatly
what do you think happen with other salts?
they use the same NACL mainly mined in a salt mines and add the rest
precipitation will come only when the mineral concentration is higer than the water capacity and that's the way to produce NACL and other minerals in different ponds with different depth/concetration
