Modified date: 23/04/2023. Copper (Cu) ore is a naturally occurring mineral deposit that contains copper in varying concentrations. It is an important industrial metal that has been used by human civilizations for thousands of years due to its excellent electrical and thermal conductivity, high ductility, and resistance to corrosion. Copper is ...

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.

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores.
