In-situ recovery: mining with minimal landscape disturbance
Sometimes called in-situ leaching or solution mining, ISR initially involves drilling holes into the ore deposit. Fracturing technologies may then be used to create open pathways in the deposit for leaching solution to penetrate. The solution is pumped into the fractured ore body, dissolving the metals into the leach solution, which is then ...
