Uranium mining by in-situ leaching

2009-12-26  Under favourable geological-hydrogeological conditions, the process of in-situ leaching is carried out by injecting the suitable solvent into the orebody through injection holes. The solvent is allowed to pass / flow through the ore body for desired period dissolving the desired metal content and the pregnant solution is then recovered through production well by pumping.(Fig.3). The pumped out solution pass through normal hydrometallurgicall route in which uranium
