SoS Minerals Madagascar ion adsorption deposits, inorganic leaching of rare earth elements (NERC Grant NE/M011232/2)
Data from experiments on rare earth element leaching from ion adsorption deposits. Columns experiments of leaching from a Madagascar ion-adsorption soil. Six soil columns for two deposit types with different starting/operational conditions. Data reported are the volume, pH and conductivity, and the molar concentrations of each eluate fraction for the metals, ammonia and Cl.

Flow through column experiments, with the eluate collected at high temporal resolution and analysed for Al, ammonia, Cl, pH, conductivity and all lanthanides (not Pm). Performed using chromatography columns (Omnifit EZ-AA 25mm/400mm) with an internal diameter of 25 mm and two adjustable end-pieces fitted with 5 um pore PTFE frits. Columns were pre-conditioned by circulating, in a closed loop, a small volume (< 300 mL) of MQ water for >7 days. Filled conditioned columns were connected to a peristaltic pump tube (Tygon S3™ E-LFL, 0.1 or 0.06 mL min-1flow rate) clamped onto a fixed flow rate pump (Bran Luebbe). Flow rate was ultimately governed by the balance of the input pressure and hydraulic pressure in the column.
