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.

Heap leaching does not generate tailings because the ore remains on the leach pad. This reduces the environmental liability at the site. The heap leach is a simple design with low capital costs in comparison to other metallurgical processes. Heap leach mines often reuse reagents in ore processing, which minimizes reagent consumption and costs.
