Outline
Based on experimental research focused on enhancing the grade of natural uranium products, reducing impurity content, and controlling moisture levels, the key factors affecting product quality were analyzed. Corresponding measures were proposed, including increasing the uranium concentration of the qualified precipitation solution, elevating the precipitation temperature, improving the washing efficiency of the precipitate slurry, and optimizing the pressure and airflow during gas-pressurized filtration. Industrial application demonstrated that after implementing these measures, the uranium grade of the product was raised from 60% to 65%, with a maximum of 67.51%, moisture content was reduced from 25%-29% to 23%-24%; and the sulfate mass fraction was below 10%. These results fully comply with the new industry acceptance standards for natural uranium products specified by the customer.
