Rare earth element (REE) and arsenic mobility in acid mine drainage (AMD) impacted soil

Autor: Glenna Thomas, Craig Sheridan, Peter E. Holm

Publikováno v: Geoderma, Vol 443, Iss , Pp 116817- (2024)

The mobility of rare earth elements (REE) and arsenic (As) from acid mine drainage (AMD) impacted soil was investigated in a column leaching study. AMD impacted soils from prominent gold and coal mining regions in South Africa were eluted with a 1 µ
