| Abstract: | The technical conditions of ammonolysis in preparing Ca(OH)2 with dolomite and ammonium chloride as raw materials were optimally chosen. The ammonia cycle test and recovery of magnesium-containing residue of ammonolysis were carried out. It is indicated that Ammonium salt method is technically feasible due to low consumption, high purity of the main product and by-product,light magnesium carbonate is fit for first-grade product of GB of China. |
