CA 2348483
The invention relates to recovering metals, such as nickel and cobalt, by phytomining or phytoextracting soils rich in metals wherein the desired metal is selectively accumulated in hyperaccumulator plants by adjusting the soil pH. The metals are ultimately recovered from above-ground plant tissues at economically acceptable levels without further contaminating the metal-containing sites. The invention also relates to metal-hyperaccumulating plants.
Récupération de métaux, tels que du nickel et du cobalt, par phytoextraction dans des sols riches en métaux, le métal désiré étant sélectivement accumulé dans des plantes présentant des propriétés d'hyperaccumulation, par ajustement du pH du sol. Lesdits métaux sont ensuite récupérés des tissus végétaux situés au-dessus du sol à des niveaux économiquement acceptables, sans contaminer encore plus les sites contenant lesdits métaux. La présente invention concerne également des plantes ayant la propriété d'hyperaccumuler des métaux.
