Lai, Lee, Huang, and Wu (2008) developed a combined acid-leaching and fluidized-bed electrolysis process. In their study, the electrolytic cell was equipped with a glass bead medium, an iridium oxide mesh anode, and a stainless steel plate cathode. The target metals (Mo, Ni, and V) were first recovered in the first stage of leaching and then further recovered in the subsequent fluidized-bed electrolytic cell (Figure 14.9). 

The effect of the degree of regeneration of the resin on the degree of extraction of a solute was measured by Slater using a seven stage unit. The results are shown in Fig. 39 for the extraction of uranium using a fluidized bed slurry of a strong base resin in a 10% uranium ore leach slurry.
