  • Copper extraction

    Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.
