Metals, Extracting metals, displacement reactions
Phytomining. Plants absorb small quantities of metal ions through their roots. The plants are burnt as a renewable form producing electricity. If the metal is copper, sulfuric acid is added to make copper sulphate. In both phytomining and bioleaching, iron is added to displace the copper. Finally electrolysis is used to get pure copper metal.

What is phytoremediation? - phy2sudoe
Tolerant plants are cultivated to take up contaminants from the soil and accumulate them in aboveground tissues which are periodically harvested, thereby removing them from the soil. For trace metals, plant biomass can be burned to produce metal-enriched ash or to obtain a bio-ore of economic value (the process is then known as phytomining).
