There is currently an exponential growth in the global demand for critical minerals, particularly lithium, to meet clean energy and decarbonisation objectives. However, sustainable supply of these minerals at risk due declining ore grades, available extraction processing technologies, socio-environmental concerns, geopolitical challenges. Africa hosts substantial resources, continent being positioned as a major player chain. As result, there rush Africa's mineral resources through investment...
Abstract The majority of nickel hyperaccumulator plant species have been discovered by screening using a field spot test based on dimethylglyoxime. Recently, the use portable X‐ray fluorescence spectroscopy instruments has enabled non‐destructive analyses existing herbarium collections. Given that family Phyllanthaceae globally greatest numbers hyperaccumulators, all available specimens from this family, including speciose genus Antidesma , at Forest Research Centre Herbarium in Sabah,...
Hyperaccumulator plants have the unique ability to concentrate specific elements in their shoot concentrations that can be thousands of times greater than normal plants. Whereas all known zinc hyperaccumulator are facultative hyperaccumulators with only populations on metalliferous soils hyperaccumulating (except for Arabidopsis halleri and Noccaea species hyperaccumulate irrespective substrate), present study discovered Dichapetalum gelonioides is (zinc) occur exclusively 'normal' soils,...
The rare phenomenon of plant manganese (Mn) hyperaccumulation within the Australian flora has previously been detected in field, which suggested that tree genus Gossia (Myrtaceae) might contain new Mn hyperaccumulators. We conducted first growth experiment on using a multi-factorial dosing trial to assess Mn, cobalt (Co), and zinc (Zn) (hyper)accumulation patterns selected species (G. fragrantissima G. punctata) after systematic assessment elemental profiles all holdings at Queensland...
Most nonoccupational human exposure to thallium (Tl) occurs via consumption of contaminated food crops. Brassica cultivars are common crops that can accumulate more than 500 μg Tl g–1. Knowledge uptake and translocation mechanisms in is fundamental developing methods inhibit or conversely for potential use phytoremediation polluted soils. (25 total) were subjected dosing screen accumulation. Seven high Tl-accumulating varieties selected follow-up experiments. The highest accumulating...
The content of different Microcystis biochemical components, including total polysaccharides (TPS), proteins, and RNA, were analyzed at growth rates obtained under varying light intensities, temperatures, nutrient concentrations. Higher intensity temperature yielded a higher specific rate Microcystis, but the 2 culture media did not significantly affect in current study. differences cellular TPS, protein, RNA temperatures (20 25 °C) significant both intensities. intensities (30 60 μmol...
Abstract Rare earth elements are increasingly required for use in modern high-tech components, and primary production is necessary to meet the demand. Reprocessing legacy metallurgical tailings advantageous, as material has already been mined, beneficiated, upgraded, contained a single accessible location. The Mary Kathleen uranium process Queensland, Australia, provides an opportunity this. geology historic methods mine described along with known characteristics of material. Conventional...
Abstract Agromining is an emerging technology that utilizes selected ‘metal crops' (= hyperaccumulator plants) to extract valuable target metals from unconventional resources for profit mineralised soils. Growth characteristics, shoot metal concentrations, and agrominable locations are important considerations in economic agromining. Globally, the greatest potential nickel (Ni) agromining exists tropics. However, agronomic systems of tropical have not been previously tested. Furthermore, it...
