Web21 jun. 2024 · We evaluated the effect of uranium bioleaching and mechanism by microwave pretreatment on uranium embedded in granite. The maximum uranium bioleaching ratio reached 93.1% after an ore sample was pretreated with microwave at 10 kW for 10 min, which was approximately 20% higher than untreated. After microwave … 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.
