Abstract

La présente invention concerne un procédé de production de sels à partir d’une saumure issue du dessalement d’eau de mer. Le procédé peut en outre permettre de récupérer sélectivement du NaCl, du CaSO4, de la kaïnite, de la carnallite, du sulfate de magnésium, de la struvite, de la newberyite, ou encore du bitartrate de potassium.
