1·The dolomite is calcined to form the mixture of calcium oxide and magnesia, then the mixture is extracted by ammonium chloride solution and ammonium sulfate solution respectively.

通过对煅烧后的白云石中所含的氧化钙和氧化镁，分别采用氯化铵溶液和硫酸铵溶液进行浸提，使其中的钙、镁得到较好的分离。

2·Magnesia calcined from magnesite as raw material, superfine magnesium hydroxide has been produced by hydration.

以菱镁矿煅烧所得氧化镁为原料，水化制备超细氢氧化镁。

3·Research on the composite magnesia cement of the caustic dolomite and the calcined magnesite;

指出欠烧或过烧菱苦土的采用是造成氯氧镁水泥硬化体胀裂的根本原因。
