How iCON Fine Mineral Recovery Works The iCON Gravity Concentrator is designed to capture all heavy minerals including Gold, Silver and PGMs. It uses a centrifugal field to concentrate very fine, free minerals that are not recoverable using the traditional techniques of small scale and artisanal miners.
In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ.In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining.
