A METHOD FOR MANUFACTURING OF MgO BY USING NaOH AND LIME MILK

摘要

The present invention relates to a method for producing magnesia using caustic soda and lime oil, and its purpose is to precipitate magnesium ions in seawater using caustic soda (NaOH) and lime oil (Ca (OH) ₂ ), which is relatively simple. The purpose of the present invention is to provide a method of manufacturing high purity MgO having a purity of 99% or more.;The present invention for achieving the above object in the method for producing MgO using seawater, by mixing and mixing 0.21-0.43% by weight of NaOH and less than 0.083% by weight of Ca (OH) ₂ to obtain a precipitate, A summary of the method for producing magnesia using caustic soda and lime oil, in which the precipitates are heat-treated at 500 to 700 ° C.
