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.

在围绕提高天然铀产品铀质量分数、降低杂质含量及控制水分等方面开展试验研究的基础上，分析了影响产品质量的主要因素，并提出了通过提高淋洗合格液铀质量浓度、提升合格液沉淀温度、洗涤沉淀料浆、优化产品压缩气体压滤压力及风量等措施，提升天然铀产品质量。工业应用表明，采取综合措施后，矿山天然铀产品中铀质量分数由60%提升至65%，最高可达67.51%；水分由25%~29%降低为23%~24%；质量分数低于10%，满足了客户提出的天然铀产品收购要求。
