摘要：

The oxidation efficiency and leaching rate of ozone micro-nano bubbles (OMNBs) on UO2 and sandstone uranium ore were explored and evaluated through a batch oxidation experiment of sandstone uranium ore and a continuous flow oxidation experiment of UO2. OMNBs can accelerate the rate of oxidative leaching. Oxidation mainly relies on ozone oxidation. Oxidation of sandstone uranium ore by OMNBs was feasible, and OMNBs may solve current problems encountered in production practice. The continuous flow experiment verified the feasibility of the large-...
