Leaching behavior of uranium and vanadium using strong sulfuric acid from Korean black shale ore

摘要

The present scientific study focused on leaching behavior of uranium and vanadium from Korean domestic ore. The leaching process experimental conditions optimized for uranium and vanadium metals recovery from Korean domestic ore and developed the basic experimental procedures such as time, particle size, acid influence, temperature effect and pulp density (PD) behavior. Acid influence on leaching process was tested and noted that 2.0 M sulfuric acid concentration is the optimized conditions for present study. The time influence on leaching process was observed and its optimized 2 h for complete leaching process. The temperature influence tested and optimized the 80 ℃ for complete leaching process and PD is 50 %(wt%). The bench scale experiments developed in a laboratory and tested in pilot level each batch 100 kg of ore sample.
