Rhenium (Re) is an extremely rare and precious element that is mainly used in the construction of aerospace components and satellite stations. However, an efficient and simple method for preparing Re has yet to be devised. To this end, we investigated the vibrational spectrum of ammonium perrhenate (NH4ReO4) using the CASTEP code based on first …
Abstract. The scattered rhenium in the environment around copper and molybdenum mines and copper processing factories is a potential source for rhenium

The article presents the results of oxidative leaching of lead sludge from copper production in order to extract rhenium into solution. The optimum regimes for product leaching man-made product in the presence of sodium peroxocarbonate Na2CO3·1.5H2O2 has been established: Experimental work was carried out under the following conditions: oxidant …
Maximum removal of rhenium (75-84%) and molybdenum (85%) were obtained at pH 2.0; Langmuir isotherm showed the maximum yeast adsorption capacities toward rhenium ions ranged between 7.7 and 33 mg ...
Rhenium is one of the scarcest (7 × 10 −8 %) and most broadly dispersed elements on Earth's upper crust. Because of its rarity and distinguishing physicochemical …
The scattered rhenium in the environment around copper and molybdenum mines and copper processing factories is a potential source for rhenium production. Phytomining is an …
The known capacity of plants to potentially hyperaccumulate Re (formal threshold for Re hyperaccumulation has not yet been defined) and the high price of this metal, make …
One such example is phytomining, a technique that employs plants with the ability to accumulate astonishing amounts of metals in their tissues. These plants, called hyperaccumulators, can be used to retrieve metals such as Ni or Au from ultramafic soils and mine tailings, respectively. ... (Ni), cobalt (Co), thallium (Tl), and rhenium (Re), in ...
economic viability of Rhenium phytomining and expected a profit of 3906 US$ ha-1 harvest-1 from the recovered Rhenium under phytomining. In another research, Ni phytomining was identified as a highly profitable agricultural technology for two …
The total Rhenium concentrations in the plant shoots ranged from 23.08 mg kg -1 to as high as 520.78 mg kg -1, and in plant shoots from 0.09 mg
Rhenium is a valuable metal (Naumov 2007; Novo et al. 2015) and it can be accumulated in plants in quantities that are potentially profitable for phytomining (Bozhkov et al. 2012; Novo et al. 2015).

Ultramafic areas are critical for nickel (Ni) phytomining due to the high concentration of this element in their soils and the number of hyperaccumulators they harbor. The aim of the present study was to evaluate the potential of the Morais massif, an ultramafic area in Portugal, for phytomining using the hyperaccumulator species Alyssum serpyllifolium subsp. …

Based on strategic considerations, Bozhkov and Tzvetkova studied the feasibility of harvesting rare-earth elements (rhenium) with phytomining. In addition, rhenium levels in alfalfa and clover were as high as 35.090 and …
DOI: 10.17014/ijog.v1i1.171New technology is needed to protect the safety and health of communities and the environment at ASGM locations in Indonesia. This technology must be simple, cheap, easy to operate, and financially rewarding. A proven option that should be promoted is phytoextraction, a farming activity that could develop agriculture as an alternative …
Rhenium (Re) is one of the scarcest and more broadly dispersed elements on Earth. Due to its paucity and high demand by the aerospace and petroleum industries, it is also one of the most valuable ...
Phytomining is a newly emerged technology in which hyperaccumulator plant species are cultivated on metal-rich medium for commercial metal recovery. The technology is …
Hairy roots were used to investigate cadmium uptake by Thlaspi caerulescens, a metal hyperaccumulator plant with potential applications in phytoremediation and phytomining.
Our approach for rhenium phytorecovery from soils includes 3 main points: a) to carry out regional investigation on the rhenium distribution in the vegetation of ore dressing region; b) to find the …
It has unique physicochemical properties that allow its use in preparation of high-temperature superalloys; rhenium improves the physicochemical properties of Ni-Re, W-Re, Pt-Re, and …
In the present work, we aimed to focus on the identification and characterization of the heavy metal-tolerant plant species growing spontaneously at the tailings site of the Sarcheshmeh copper mine, south of Iran. Our aim was to find the plant species that were potentially useful for phytoextraction purposes. The concentrations of As, Cu, Mo, Ni, Zn, and Re were analyzed in …
