Abstract
A process method for preparing magnesium oxide from dolomite includes the following steps: S1, pretreating dolomite to obtain the calcined dolomite; S2, hydrating the calcined dolomite according to the solid-liquid ratio, controlling the hydration temperature and the hydration time, filtering, washing and drying after hydration to obtain the hydration product; S3, configuring a complex solution, using the sodium hydroxide solution to adjust the pH value to 8-10; S4, performing the complexation reaction by mixing the hydration product in S2 with the complex solution in S3, and controlling the complexation temperature and the complexation time, obtaining the magnesium oxide by filtration, washing and drying after the reaction is completed. The invention uses dolomite as raw material, and the amount of magnesium hydroxide produced by magnesium oxide at a specific hydration temperature and hydration time can be ignored.
