【美国《工程与采矿杂志》1983年1月第112页报道】英比尔公司在其就地浸取试验性工程处克朗波因特附近,正在进行溶解采铀后,应用硫化钠净化地下水的试验。硫化钠试验和近期应用赤抗坏血酸钠(sodiumerythorbate)的试验,是莫比尔为达到全面商业生产而进行的中间试验中所用的第三种工艺方法。在适当位置应用碳酸氢钠溶解铀之后,采用上述两种试剂作试验,得到了新墨西哥州环境改善局的核准。环境改善局说,注入新的化学试剂“预期会加速不断发展的含水
[Journal of Engineering and Mining, USA, January 1983, p 112] Inlbourne uses sodium sulfide to purify groundwater after it is undergoing uranium mining in the vicinity of its in-place leaching experimental engineering office in Crown Point. . The sodium sulphide test and the recent application of sodium red ascorbate (Sodiumerythorbate) are the third process used in the intermediate tests conducted by Mobile to achieve full commercial production. After application of sodium bicarbonate to dissolve uranium in place, the above two reagents were tested and approved by the New Mexico State Environmental Improvement Agency. The Environment Improvement Agency said that the injection of new chemical reagents "is expected to accelerate the development of water
