  Copper solvent extraction: status, operating practices, and challenges secondary sulphide, containing to % acidsoluble copper. The operations are typically heap and dump leaching, with permanent pads (rather than on–off pads) to minimize operational costs. The SX circuits are often configured for series–parallel or allparallel operation, as this maximizes copper production .

  The process is called phytomining and it can also be used to extract metals from contaminated land. Brassicas (the cabbage family) can extract metals including cadmium, cobalt and nickel. Copper can also be extracted by displacement from a copper salt solution using scrap iron. Pure copper (99·99%) is needed for good electrical conductivity.
