    In the early 1960s, for example, to be exploitable, the minimal acceptable mineral content of copper ore was 0.8%, but a minimal metal content of 0.3% is now considered to be adequate. Another example of this trend is the Rossing uranium mine in Namibia, which has been opened despite a metal content of only a few hundred grams per ton of ore

    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 L hour −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
