Conventional mining produces tailings, runoff, and considerable land disturbance—all requiring significant rehabilitation. With in-situ leach mining methods (see diagram at right), disturbance is reduced because only multiple boreholes are drilled for recovery. Rehabilitation is much simpler, consequently the number of in-situ uranium mining ...
