Background：The In situ leaching (ISL) of uranium mining is an important method to nuclear reactors for sustainable utilization of nuclear energy. Surfactants have their potential role in the increasing permeability of ore bed and the leaching rate of uranium in ISL. Purpose: The aim is to study the application of surfactants in ISL and identify whether the addition of surfactants have any effect on the resin property. Method: The influence of several surfactants such as OP-10

FSO

LVA

LF221 and their complexes on resin adsorption and elution of uranium from production solutions for ISL were researched by column experiments. Results: The results show that adding 50−100mg•L−1 different surfactants and their complexes into the production solutions for ISL has no significant influence on the resin adsorption and elution of uranium

in which the adsorption curve

sorption capacity of resin and recycling of resin are the same with the experimental results without surfactants. The adding of surfactants can increase the peak concentration of uranium in eluents and reduce the residual uranium content in resin

which promotes the elution efficiency. It also showed that the complexes of OP-10 and FSO are the best among various surfactants. Conclusion: As mentioned above

the surfactants can be used in ISL of uranium mining very well.Cited
