The purpose of neutralization is to remove chlorine from Sb4O5Cl2 and convert it to Sb2O3. Generally, ammonia is used as a neutralizing agent: Further, adding an appropriate amount in the same time with the agent and transformation agent, can greatly reduce the content of impurity elements such as iron oxide, lead antimony (≤0.001%), antimony oxide and a cubic crystal form transformed by the orthorhombic, greatly reduce The photosensitivity of Otaru is very beneficial for maintaining whiteness. In the neutralization process, the neutralization washing liquid is used to adjust the slurry, and it is neutralized under normal temperature conditions. The pH of the neutralization end point is about 7.5, and it is stable for 10 to 20 minutes. Then, filter and wash, medium-sized and above factories should use filter belts, filter belts should be equipped with filter section and washing section, small-scale factory vacuum pumping filter, washing with pure water, washing to the end point (more than 8 times) When using AgNO3, the wash solution was checked for no white precipitate. The quality of high-purity yttrium oxide products directly prepared from brittle sulphide lead ore concentrate and sorghum lead anode slime is shown in the table below. The main components and impurity element content of high-purity cerium oxide directly prepared by the new chlorination-hydrolysis method and AC method (%) No. Sb 2 O 3 Pb As Fe Cu Bi Se S Cl Raw materials and methods 2 99.83 0.0012 0.0098 0.0019 0.00069 0.0062 0.002 0.0013 0.013 Brittle sulphur bismuth concentrate, New chlorination-hydrolysis 3 99.91 0.0021 0.017 0.005 0.0029 0.0054 0.0023 0.0010 0.012 4 99.81 0.0014 0.021 0.0005 0.00026 0.0052 0.0024 0.0010 0.016 5 99.85 0.000 0.00017 0.0005 0.00001 0.000 0.000 - 0.011 Sorghum lead anode slime, AC method 7 99.85 0.000 0.0000 0.0006 0.000 0.000 0.000 - 0.0095 Note: The new chlorination-hydrolysis method does not take the arsenic removal method; the AC method is more than one new reduction solution of the new chlorination-hydrolysis method, and the pure SbCl3 is produced and then hydrolyzed.
