| Abstract: | The paper asks about extracting magnesium oxide from the brine. Brine-soda method to the purification of brine by adding sodium carbonate, the preparation of basic magnesium carbonate, basic magnesium carbonate magnesium oxide after calcination. The experimental results show that the Barium chloride concentration of 0.13 mol/L, and the water bath temperature of 40 ℃, feed rate the 5 mL/min, aging time for lh brine purification best. The ratio of raw materials to 110 %, the reaction temperature is 60℃, reaction time was 30 min, and Magnesium oxide yield. |
