  • Sulfuric acid injection in copper heap leaching LEWA

    Sulfuric acid injection in copper heap leaching LEWA

    The leaching reagent dilute sulfuric acid is sprayed through sprinklers on top of the heap pile and allowed to trickle down through the heap, where it dissolves the copper from the ore. The resulting solution of sulfuric acid and copper sulfate is collected in a small pool. Copper concentration is around 65. Next step is solvent extraction.

    TENORM Copper Mining and Production Wastes

    Sep 14, 2016 During in-situ leaching, rather than removing soil and rock to reach copper deposits, acids are injected into ore bodies via wells. The PLS is captured in production wells and pumped to a leach plant where the copper is later recovered. High levels of TENORM have been found in the PLS of two in-situ leach operations in Arizona.
