Abstract: PURPOSE:To increase the purity by decomposing dolomite under heating, then throwing the resultant oxide into water for preparation of an emulsion thereof, carrying out exchange adsorption of Ca therein using a cation exchange resin for separation of Mg components from Ca and calcining the resultant Mg components. CONSTITUTION:Dolomite is initially heated at 700-800 deg.C to decompose MgCO3 component and further heated at >=800 deg.C to decompose CaCO3 component and the resultant oxides composed of MgO, CaO, etc., are thrown into hot water to prepare a dolomite emulsion. To the emulsion, an ion-exchange resin (H-R) is added so as to convert dissolved Ca(OH)2 to Ca-R2 by an ion-exchange reaction. The Ca-adsorbed resin (Ca-R2) is then separated from a MgO-containing suspension and treated with a dilute hydrochloric acid in order to be converted to CaCl2 and Ca component is obtained in 85-90% yield. The MgO-containing suspension is filtered to collect MgO and the resultant MgO is calcined at >=1000 deg.C to be converted MgO clinker. The obtained MgO clinker is further calcined at >=1500 deg.C, thus obtaining the objective MgO having 96-98% purity in 70-85% yield.
