Abstract

En fremgangsmåte for fremstilling av magnesiumhydroksid fra sjøvann til bruk ved produksjon av magnesium metall, hvor magnesium hydroksid blir utfelt med natriumhydroksid som er fremstilt fra sjøvann ved hjelp av dialyse.A process for producing magnesium hydroxide from seawater for use in the production of magnesium metal, wherein magnesium hydroxide is precipitated with sodium hydroxide prepared from seawater by dialysis.
