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

In-Situ Leaching Borehole Mining

2019-1-14  In situ leaching does not include dump or heap leaching where the ore is blasted and/or dug and placed in areas specially prepared for leaching, but is reserved for the process where chemical solutions are circulated through the ore body. Although the ore may be blasted to increase permeability for in situ leaching,

Methods and Techniques of Uranium Mining nuclear

In-Situ-Leaching (ISL). In-situ leaching, also known as in-situ recovery, is a mining process different from the conventional method in that it uses a chemical process to separate the uranium in the earth’s crust from the surrounding rock. In-situ is a Latin phrase that translates literally to “on site” or “in position.”
