  • 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.

    Kinetics of nickel leaching from lownickel matte in ...

     · The effect of the initial sulfuric acid concentration on the leaching of nickel is shown in Fig. 3 (c). The experimental evaluation indied that there were fewer and fewer hydrogen sulfide bubbles with the extension of the reaction time. The reaction took place very quickly in the first 1200 s. When the reaction time exceeds 1800 s, the leaching efficiency of nickel reaches 90% at 4 mol L
