In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 Lhour −1 m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.
