Phytomining. Some plants absorb metal compounds (including copper) when they grow. The plants can then be burned and the metal is extracted from the ash. 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.
Phytomining and Bioleaching - GCSE Triple Award Revision ...
Phytomining involves growing plants on top of low grade ores. The plants absorb copper ions through their roots The plants are then burnt to ashes containing copper ions. These ions are leached from the ash using sulfuric acid. Scrap iron can then be used to displace the copper from the leachate.

Bioleaching Process - Mining Fundamentals
Jan 10, 2014 · Bioleaching, or microbial ore leaching, is a process used to extract metals from their ores using bacterial micro-organisms. The bacteria feed on nutrients in the minerals, causing the metal to separate from its ore. The metals commonly extracted using this process include gold, silver, zinc, copper, lead, arsenic, antimony, nickel, molybdenum ...
Phytoremediation - an overview | ScienceDirect Topics
Some important metals, such as Ni, Se, Zn, and Fe can be recovered from the phytoremediation process of phytomining and biofortification. The recovery of metals from metal contaminated sites, using high biomass producing plants is known as phytomining.
