Farming to harvest metals

[DrBob2]

@jerryab2

As the metal (in the plant) is more pure than mined ore, extracting the metal (as part of the complete refining process) will be less expensive than reaching the same purity level with mined ore.

As with other “recycling” the costs are dependent upon the ease of collection and the concentration. Also, IIRC, the plants used in phytoremediation are rather indiscriminate in their uptake.
