Applications of a complex surfactant developed in-house to in-situ leaching of lowpermeable sandstone uraniumdeposits are described based on results from agitation leaching, column leaching, resin adsorption, and elutionexperiments using uranium containing solution from the in-situ leaching site. The results of agitation leachingexperiments show that adding surfactant with different concentrations into leaching solution improves theleaching rate of uranium. The maximum leaching rate of uranium from agitation leaching reached 92.6% at anadded su...
