This paper focuses on the "CO2+O2" in-situ leaching uranium process of the Qianjiadian uranium deposit, and conducts an in-depth investigation into the relationship between filter length, leaching recovery rate, and operating water volume. Actual field data are used for analysis, and the results show that there is a strong positive correlation between filter length and operating water volume: the operating water volume increases significantly in the filter length of 7-11 m, with an average growth rate of 5.2% per meter; while the growth slows down in the filter length of 12-18 m, with an average growth rate of 1.3% per meter. In contrast, a strong negative correlation is observed between filter length and leaching recovery rate: the leaching recovery rate decreases gently in the filter length of 7-11 m, with an average decline rate of 0.75% per meter; the decline accelerates in the filter length of 12-14 m, with an average decline rate of 2.0% per meter; and it drops sharply in the filter length of 15-18 m, with an average decline rate of 3.67% per meter. Based on the above analysis, it is determined that the optimal filter length range for the "CO2+O2" in-situ leaching uranium process of the Qianjiadian uranium deposit is preferably 7-9 m. For ore segments with larger ore body thickness, the filter length can be appropriately adjusted within the range of 16 m, but shall not exceed 16 m.

聚焦钱家店铀矿床“CO2+O2”地浸采铀工艺,深入探究过滤器长度与浸采率、抽液量之间的关系。基于实际运行数据进行分析,得出过滤器长度与抽液量呈强正相关,在过滤器长度为7~11 m时,随过滤器长度增加,抽液量增长显著(平均增长率5.2%/m);在过滤器长度为12~18 m时,随过滤器长度增加,抽液量增长放缓(平均增长率1.3%/m)。过滤器长度与浸采率呈强负相关,在过滤器长度为7 ~ 11 m时,随过滤器长度增加,浸采率下降平缓(平均降幅0.75%/m);在过滤器长度为12~14 m时,随过滤器长度增加,浸采率降幅增大(平均降幅2.0%/m);在过滤器长度为15~18 m时,随过滤器长度增加,浸采率大幅下降(平均降幅3.67%/m)。根据研究结果,建议在钱家店铀矿床“CO2+O2”地浸采铀工艺中,过滤器长度宜优先采用7~9 m的最优区间;对于矿体厚度较大的矿段,可在16 m范围内适当调整,但不应超过16 m。

聚焦钱家店铀矿床“CO2+O2”地浸采铀工艺,深入探究过滤器长度与浸采率、抽液量之间的关系。基于实际运行数据进行分析,得出过滤器长度与抽液量呈强正相关,在过滤器长度为7~11 m时,随过滤器长度增加,抽液量增长显著(平均增长率5.2%/m);在过滤器长度为12~18 m时,随过滤器长度增加,抽液量增长放缓(平均增长率1.3%/m)。过滤器长度与浸采率呈强负相关,在过滤器长度为7 ~ 11 m时,随过滤器长度增加,浸采率下降平缓(平均降幅0.75%/m);在过滤器长度为12~14 m时,随过滤器长度增加,浸采率降幅增大(平均降幅2.0%/m);在过滤器长度为15~18 m时,随过滤器长度增加,浸采率大幅下降(平均降幅3.67%/m)。根据研究结果,建议在钱家店铀矿床“CO2+O2”地浸采铀工艺中,过滤器长度宜优先采用7~9 m的最优区间;对于矿体厚度较大的矿段,可在16 m范围内适当调整,但不应超过16 m。

This paper focuses on the "CO2+O2" in-situ leaching uranium process of the Qianjiadian uranium deposit, and conducts an in-depth investigation into the relationship between filter length, leaching recovery rate, and operating water volume. Actual field data are used for analysis, and the results show that there is a strong positive correlation between filter length and operating water volume: the operating water volume increases significantly in the filter length of 7-11 m, with an average growth rate of 5.2% per meter; while the growth slows down in the filter length of 12-18 m, with an average growth rate of 1.3% per meter. In contrast, a strong negative correlation is observed between filter length and leaching recovery rate: the leaching recovery rate decreases gently in the filter length of 7-11 m, with an average decline rate of 0.75% per meter; the decline accelerates in the filter length of 12-14 m, with an average decline rate of 2.0% per meter; and it drops sharply in the filter length of 15-18 m, with an average decline rate of 3.67% per meter. Based on the above analysis, it is determined that the optimal filter length range for the "CO2+O2" in-situ leaching uranium process of the Qianjiadian uranium deposit is preferably 7-9 m. For ore segments with larger ore body thickness, the filter length can be appropriately adjusted within the range of 16 m, but shall not exceed 16 m.
