The use of sodium hypochlorite and thiourea as reagents-solvents for extracting gold from spent uranium deposits by underground leaching was determined as optimal based on the laboratory experiments. Activated carbon of the AG-3 grade has been determined as the most effective for gold extraction from the productive solution. Qualitative parameters of underground leaching, lithology thickness, planar and cross-sectional shapes, as well as filtration properties of wells along with infiltration flow irrigation zones have been established through bench-scale testing. A new model of solution filtration by high-pressure and free flooding onto the reservoir has been developed using the results obtained.
