  • In situ leach Wikipedia

    Insitu leaching (ISL), also called insitu 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.

  • High Pressure Acid Leach Caldera Engineering

    High Pressure Acid Leach (HPAL) is a process used to extract nickel and cobalt from laterite ore bodies. The HPAL process utilizes elevated temperatures (roughly 255 degrees Celsius), elevated pressures (roughly 50 bar or 725 psi), and sulfuric acid to separate nickel and cobalt from the laterite ore.

  • Extraction of Tin and Copper by Acid Leaching of PCBs

    The leaching time increases drastically when the concentration of nitric acid was reduced. For greater than 50% concentrated acid, reaction was instant and finished within 15 minutes. Whereas for less than 20 % acid concentration, it took about two hours for the reaction to complete.
