Rhenium Phytomining
Review on metal extraction technologies suitable for critical …
Two examples of this are indium and rhenium. Indium is used in electronics, including touchscreens and flat-panel display screens (Shanks et al., 2017), and rhenium is used in high temperature superalloys and in platinum–rhenium catalyst (John et al., 2017), resulting in high demand for both metals.

Theoretical Prediction of Rhenium Separation from …
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 …

Phytomining: New Method for Rhenium Production
Abstract. 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 inexpensive and environmentally friendly method for extracting rhenium and remediating exhausted soils near copper mines and ore-dressing regions.
