Phytomining - ScienceDirect

Phytomining is the production of a `crop' of a metal by growing high-biomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced. Pioneering experiments in this field might lead to a `green' alternative to existing, environmentally destructive, opencast mining practices. Phytomining for a range of ...

Phytomining and Bioleaching. Metal ores are a finite resource which are in limited supply. New methods of copper extraction exploit waste ores and low grade ores. 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 ...

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. Copper can also be extracted by displacement from a ...

However, phytomining is a slow process, and produces fairly small amounts of metal compared with conventional techniques. Another way of using phytomining is to remove toxic metals from contaminated ground. If we grow hyperaccumulators on contaminated ground, they will remove the toxic substances from the soil, making it safe to use again. Bioleaching uses bacteria, rather than plants, to ...
