In addition, dissolved across the setups after weeks 3 and 4 were 0.384 mg/L and 1.097 mg/L respectively. The results demonstrate that giant taro can solubilize and sorb and is a potential candidate for recovering from the environment, low-grade stockpiles and heaps as well as mineralised soils in an eco-

Phytomining: Trends in Plant Science

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.

Phytoextraction of gold and copper from mine tailings with ...

Gold occurs with copper in mine tailings. If gold phytomining is to be used to recover gold, the effect of copper on plant health must be considered. Both Helianthus annuus and Kalanchoe serrata accumulate gold, but show differential uptake of copper. Geochemistry, suitability of plant to climate, and uptake of metals other than gold should be considered. The potential for economic …
