• In situ leach - Wikipedia

    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.

  • Innovations in Copper Mineral Processing Technology

    Reasons for Copper Ore Sorting cont. • Pre-concentrate feed into high-grade and low-grade stockpiles: – Optimize multiple process streams i.e. send ore to either mill, heap leach or smelter. – Allows smaller mills to be built or increase capacity of an existing mill. – Manage ore blending programs more effectively.
