Accumulation and fractionation of rare earth elements (REEs) in wheat: controlled by phosphate precipitation, cell wall absorption and solution complexation

Accumulation and fractionation of rare earth elements (REEs) in wheat: controlled by phosphate precipitation, cell wall absorption and solution complexation.

Previous studies on rare earth element (REE) bioaccumulation have focused on their accumulation rate and fractionation, but the processes involved remain unclear. In this study, the accumulation and fractionation of REEs in wheat (Triticum aestivum L.) were investigated using solution culture with exogenous mixed REEs. A decrease in REE contents was observed from the roots to the tops of wheat....

Concentration and recycling of rare earth elements (REEs) from iron mine waste using a combination of physical separation methods

This study aims to investigate and optimize the effects of the main parameters including the particle size, gravity and magnetic separation combination, high gradient magnetic separation, magnetic field intensity, shaking table slope, washing water flow, and electrostatic separation upon the rare earth element (REE) recoveries from iron mine waste. The electron microprobe showed that high amoun...

Rare earth elements adsorption onto Carrizo sand: Influence of strong solution complexation

Accumulation and fractionation of rare earth elements in atmospheric particulates around a mine tailing in Baotou, China

Rare earth elements (REEs) have been increasingly emitted into the 8 atmosphere with a worldwide increase in use of these metals. However, the research 9 on REEs in atmospheric particulates is fairly limited. In this paper, atmospheric 10 particulates including total suspended particulate (TSP) matter and particles with an 11 equivalent aerodynamic diameter less than 10 μm (PM10) were collected...
