Abstract
Metals with an average crustal abundance of <0.01 ppm, which are high in supply shortage due to soaring demand, can, under the excessive environmental risk and <1% recycling rate of their production, be termed as ‘critical’ in a limited geo-boundary. A global trend to the green energy and low carbon technologies with geopolitical scenario is challenging for the sustainable reclamation of these metals from secondary resources. Among the available processes, bio-reclamation can be a sustainable technique for extracting and concentrating these metals. Therefore, in the present paper, the potential reclamation of critical metals (including rare earth elements, precious metals, and a common nuclear fuel element, uranium) via their interaction with microbe/s has been reviewed.
Highlights
The rare earth elements (REEs) and precious metals (PMs) have remained in metallurgical attraction for a long time
The results revealed a linear enhancement in Y extraction with time, which could reach has been studied for yttrium extraction from the waste cathode ray tube (CRT) glass [29]
Extremophile, acidophilic methanotrophic Methylacidiphilum fumariolicum, Pol et al [39] observed observed that the function of methanol dehydrogenase (MDH) in this bacterium strictly depends on the presence of REEs
Summary
The rare earth elements (REEs) and precious metals (PMs) have remained in metallurgical attraction for a long time. The availability of these metals largely influences the energy supply; country’s economy, export business, job creation and geopolitical relation of two individual countries [5], can be Metals 2017, 7, 207; doi:10.3390/met7060207 www.mdpi.com/journal/metals. The availability of these metals largely influences the energy supply; country’s economy, export business, job creation and geopolitical relation of two individual countries [5], pronounced as ‘strategicascritical metals’. Reclamation of compounds to transfer across the trophic levels of food-chain and bioaccumulating in living critical metals from their alternative secondary resources can betheir a game-changer by overcoming the organisms. Reclamation of critical metals from alternative secondary resources geo-boundary limitation, thethe supply risk and controlling the environmental damage by can be a game-changer bymitigating overcoming geo-boundary limitation, mitigating the supply risk and mining of their primary ores.
