• In-Situ Recovery of Critical Technology Elements

    Jan 01, 2016· In line with the increasing environmental demands and restrictions for mining projects worldwide, in-situ recovery of ore (ISR, also known as in-situ leaching) has become an attractive alternative to existing open-pit and shaft mining operations, mainly because ISR only recovers the actual ore and therefore prevents production of tailings.
