| Abstract: | Through calcination,assimilation,carbonation,pyrolyzation and drying,basic magnesium carbonate with the content of CaO less than 0.1% was prepared from dolomite.And then high-purity magnesia with the content of MgO more than 99% was gained by calcining the basic magnesium obtained above.The influences of calcination temperature of the dolomite and the assimilation conditions on assimilation efficiency,that of the final pH of carbonation on carbonation efficiency,and that of the addition of(NH4)2C2O4 and the... |
