Abstract
세균침출에 의한 저품위 우라늄광으로부터 우라늄 회수를 목적으로 침출에 관여하는 균주의 분리ㆍ동정실험과 우라늄 침출에 대하여 연구하였다. 우라늄 침출에 관여하는 균주를 분리ㆍ동정하기 위하여 보성 탄광, 달성 동광산 및 일광 동광산의 갱내수를 채취하여 균을 분리, 배양하여 달성과 일성 동광산으로부터 Fe2+, 황화물 및 thiosulfate 를 산화하여 우라늄 침출에 적용할 수 있는 침출 세균인 Thiobacillus ferrooxidans를 분리ㆍ동정하였으며, 균주의 최적 생장조건은 30℃와pH2.5이다. 철산화세균에 의해 우라늄 원광석으로부터 10일만에 약 34-38%의 우라늄을 침출하였다.
In order to leach the aqueous uranium from the low-grade uranium ore, the studies on the identification of the iron-oxidizing bacterium associated with uranium leaching and, subsequently, the leach-ing of uranium were made. Slime samples were collected from Bosung, Dalsung, and Ilkwang mines to isolate and identify the iron-oxidizing bacteria. Thiobacillus ferrooxidans oxidizing the ferrous iron, sulfides, and thio-sulfate was then isolated successfully along with the optimal growth conditions(30℃ and pH2.5). In the presence of this iron-oxidizing bacterium 34% to 38% of the aqueous uranium could be leached out from the low-grade uranium ore within 10 days.
