It is convenient for sinter to be leached, and the secondary reaction appears little. The slurry after sinter leaching is transferred into autoclave for desilicification at about 170℃, and the siliceous modulus of solution reaches more than 200. Then some lime is added for deep-desilication at normal pressure, the siliceous modulus of solution increases more than 600 even if the Al2O3 content is more than 200g/L.The SiO2 coefficient in hydrate garnet from deep-desilication is more than 0.28. Under conditions of the addition of seed and application of novel technology of carbonization, the contents of Na2O and SiO2 in product are less than 0.37% and 0.025%, respectively.
