Method for preparing magnesium oxide raw material from dolomite ore
The invention provides a method for preparing a magnesium oxide raw material from dolomite ore, which comprises the following steps: providing a dolomite raw material, and calcining the dolomite raw material to obtain dolomite calcined powder; in an ammonium salt solution containing organic acid radicals, the dolomite calcined powder is subjected to leaching and sedimentation treatment, and filtrate and filter residues are obtained; and washing and drying the filter residues to obtain the magnesium oxide raw material. According to the method, calcium and magnesium in the dolomite can be effectively separated, the high-quality magnesium oxide raw material is prepared, and meanwhile, the method is easy to realize industrial production.
本发明提供一种利用白云石矿制备氧化镁原料的方法，包括：提供白云石原料，煅烧所述白云石原料，得到白云石煅粉；在含有机酸根的铵盐溶液中，对所述白云石煅粉进行溶浸与沉降处理，得到滤液和滤渣；洗涤所述滤渣并烘干，得到氧化镁原料。本发明可以有效地将白云石中的钙、镁进行分离，制备出高品质氧化镁原料，同时该方法易于实现工业化生产。
