In-situ recovery, or ISR, is an extraction process designed to leave a mine's physical location undisturbed. It is touted as an environmentally cleaner method of extraction. In a nutshell, in situ means “in the natural or original position,” and the process seeks to remove mineral ore from right where it sits,.ISR - In-Situ Copper Recovery - Gunnison CopperIn-situ means “in the natural or original position.” In the simplest terms, in-situ recovery (ISR) involves removing the selected minerals or metals without digging up the host rock. This creates many environmental and economic advantages over conventional extraction. In-situ extraction is not new. It has been used.
