Seawater is a rich repository of unlimited resources, which covers about 70% of the surface of earth. Although seawater gets the spotlight as a repository of new resources with the recent exhaustion and low-grading of land resources, a combination of basic knowledge and various industrial technologies regarding seawater is required in order to develop seawater resources. Despite unlimited possibilities, the development of seawater resources remains at an early stage due to said reasons. It is reported that almost every element including gold, silver, beryllium, potassium, cesium, cobalt, vanadium, nickel, chrome, copper, zinc, manganese, iron, magnesium, bromine, strontium, uranium, urea, molybdenum, etc. is contained in seawater. The problems are a technical problem of whether or not these elements contained in seawater can be extracted, and whether or not there is the economic feasibility necessary to extract at a lot of costs. The current research technologies of leading countries are limited to a method of recovering by adding an additive to seawater to precipitate, and a method of recovering rare minerals such as uranium, lithium, etc. by using an adsorbent. The present invention relates to a method of recovering specific materials (uranium, lithium, magnesium, gold, other nonferrous minerals, etc.) dissolved in seawater by desalinating seawater in a reverse osmosis method, electrolyzing the desalinated seawater to be ionized, then, gasifying at a high temperature, and separating desired materials according to each specific gravity by using a high speed centrifugal separator. Upon commercializing the technology of the present invention, the present invention can remarkably contribute to the stable resource and energy source for mankind as seawater is a rich repository of unlimited resources which covers about 70% of the surface of earth.(AA) Seawater(BB) Reverse osmosis (desalination)(CC) Electrolysis (ionization)(DD) Centrifugal separator (separation of dissolved materials)(EE) Vacuum evaporation concentrator (reduced pressure)(FF) Spraying and drying device(GG) Selection(HH) Seawater treatment chartCOPYRIGHT KIPO 2015
