A review of electrokinetic, ultrasonic and solution pulsing methods for mass transfer enhancement in in-situ processing

There is increasing interest in the in-situ leaching or in-situ recovery of metals because of the method’s potential for a lower operating cost and the potentially smaller environmental impact. Only preliminary investigations have been conducted to understand the factors that influence the rate of recovery that may be achieved in in-situ recovery operations. This review focuses on the potential of three methods to accelerate the movement of...
