with copper). “Copper is increasingly recovered by solution methods, including dump and in situ leaching. Because most copper ores are insoluble in water, chemical reactions are required to convert copper into a water-soluble form; copper is recovered from a leaching solution through precipitation or by solvent extraction/ electrowinning (SX/EW).

Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is piled into a heap on top of an impenetrable layer, on a slight slope. 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.
