T he results show that: ¹ The metal leaching rate is related to the ore size tremendously, the ore size goes smaller, the metal leaching rate is higher, the appropriate ore size is - 4mm; ºT he acid consump- tions is 61 6%~ 101 4% , the leaching rate is 791 4% ~ 871 3% , the acid consumptions is low er, it is suit- able for acid leaching; »The ideal spraying way is that continual dropping is used in the early leaching peri- od and the intermittent dropping used in the medium and final period. The results are helpful for industry experiments of heap leaching later. ey words: column leaching; uranium ore; leaching rate 70%[
