Phytomining. This process takes advantage of how some plants absorb metals through their roots; The plants are grown in areas known to contain metals of interest in the soil; As the plants grow the metals are taken up through the plants vascular system and become concentrated in specific parts such as their shoots and leaves; These parts of the plant …

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. Pioneering experiments in this field might lead to a `green' alternative to existing, environmentally destructive, …

Phytomining involves the production of a 'crop' of metals by growing high-biomass hyperaccumulators that accumulate high concentrations of metals (Robinson et al. 1999a).In contrast to simple phytoextraction techniques, the goal of phytomining is primarily to realize the economic benefits and commercialization by comprehensive use …

One aspect of phytomining is promoting phytoremediation at degraded/closed mine sites (Novo et al., 2017).The major concerns in this field are (i) survey of potential phytomining areas (ii) selection of appropriate hyperaccumulator plant species, and (iii) biomass yield from plants and ultimate metal content in dry mass (Novo …

Abstract Bioleaching of metal sulfides is performed by diverse microorganisms. The dissolution of metal sulfides occurs via two chemical pathways, either the thiosulfate or the polysulfide pathway. These are determined by the metal sulfides' mineralogy and their acid solubility. The microbial cell enables metal sulfide dissolution …
