works with solutions (substances dissolved in a liquid). use scrap iron in the solutions because iron is much higher than copper in the reactivity series, so its more reactive. so when you add iron to the compound, it pushes the copper out of the copper compound.

Soil Phytomining: Recent Developments—A Review
Phytomining (PM) is defined as the process of using plants capable of bio-extracting metals from soil in order to explore them economically. This relatively new, innovative method has been gathering significant attention in both the academic and commercial domains. Conventional mining methods are often economically unviable when applied to lean ores, and they can lead …
