Geochemical assessment of the bioavailability of platinum
Phytomining is suggested as a novel technology to obtain platinum group metals (PGMs) nanoparticles from plants grown on the mineralized soil, rock, or on mine wastes. The primary determinant of metal uptake by a plant is the bioavailability of the metal in the soil-plant system. In this thesis project, the bioavailability of PGMs of several PGM-rich materials is assessed with respect to
Phytomining: Trends in Plant Science - Cell
Sep 01, 1998· 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.

Science of Rare Earth Elements Science History Institute
The electron structure of the rare earths makes them useful as catalysts (accelerators) for chemical reactions. Cerium and lanthanum are the main rare earths used in catalytic applications, since these two metals are much more abundant and sell for much lower prices. Cerium is used in the catalytic converters on gasoline-powered cars.
GCSE CHEMISTRY - Extraction of Copper - Thermal
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.
