Growing for gold
Plants will be used to recover gold and other metals from mining wastes
Cutting-edge research will be used in a 拢375,000 project to find a plant-based alternative for the recovery of gold, silver and copper nanoparticles from mining waste.
The project, led by Scotland鈥檚 Rural College (伊人直播), will combine a plant-based technique called phytomining 鈥� where plants absorb metal ions through their roots 鈥� with an advanced biotechnological approach to retrieve the resulting metal nanoparticles from the waste.
Supported by expertise from the universities of York, Edinburgh and Nottingham, and two key players in the UK mining and nanotechnology industry - Scotgold Resources and Promethean Particles respectively - the researchers will use native UK plants to retrieve metal nanoparticles (NPs) such as gold, silver, and copper from mine tailings taken from the Cononish mine near Tyndrum.
Once the plants have undergone advanced biomass processing to retrieve the NPs, the team will then investigate the potential of using the waste for conversion into biogas or other value-added bioproducts.
The project will generate unprecedented knowledge about using phytomining to produce biogenic NPs from metal-rich wastes, facilitating a first-time assessment of their potential in the industrial, agricultural, environmental and biomedical sectors.
Additionally, it will enable the development of new biotechnology to support the R&D sector, and the design of specific high-value bioproducts from the waste biomass for commercial-scale production.
Lead researcher Dr Luis Novo, an 伊人直播 Challenge Research Fellow, said: 鈥淭he ever-growing build-up of mine waste across the planet constitutes an opportunity for the recovery of residual metals of technological significance.
鈥淭here has been increased interest in biogenic NPs due to advantages over chemically synthesized NPs. In this light, producing NPs via phytomining heralds great promise as it would represent a low-cost, eco-friendly and carbon-neutral strategy to farm nanoparticles from residues.鈥�
The research was funded by the Biotechnology and Biological Sciences Research Council (BBSRC) following a call for projects offering biotechnological solutions that reduce environmental impact in either the textile industry or the recovery of technology-relevant metals.
