Bioassisted Phytomining of Gold SpringerLinkPhytomining ScienceDirect

Bioassisted phytomining implies targeted use of microorganisms and plants for the selective recovery of the metal Metals from undissolved compounds are dissolved by applying specially chosen microorganisms and therefore become available to the hyperaccumulating plants In 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

New technique to yield gold from crop plants Times of IndiaEngineered Gold Nanoparticles and Plant Adaptation Potential

The technique of finding gold called phytomining uses plants to extract particles of the precious metal from soil Reuters Photo In poplar plants the size distribution of the gold nanoparticles appears to be somewhat modified during uptake and transport with the exception of the 50 nm gold nanoparticles which maintained their diameter and were surrounded by some unknown substances in the leaf xylem cells In this study gold nanoparticles were found more in the roots than in the leaves because the roots directly
