RB 45/00104 Recovery of lanthanons and thorium from Radium Hill barren leach liquor. Part one. Separations involving partial neutralisation.
A separation of the lanthanons was obtained by hydrolysing the unwanted liquor constituents from the oxidized barren liquor at approximately pH 4. However, this procedure was impracticable owing to the costs involved and the fact that little or no...-

RB 96/00031 Big Lake Suite not Tirrawarra Sandstone in the Moomba Field, Cooper Basin, SA.
Granodiorite core recovered from Moomba 72 has enabled recent recognition of an altered zone at the top of pre-Permian 'basement'. This altered zone has been previously misinterpreted as Early Permian Tirrawarra Sandstone. Consequently, the depth...-

RB 00695 Port Pirie residues. Barren liquor, laboratory investigations.
Trialling of precipitation and leaching techniques for the recovery of Y, Sc and heavy lanthanides from process sulphate liquors gave low recoveries. A solvent extraction process using EHPA (di-ethyl hexyl phosphoric acid) was proposed for recovering...-

SADM / Amdel Project 1/1/15 : Crocker Well and Mount Victoria uranium ore concentrate. Recovery of valuable constituents [uranium and thorium]. Final report.
An investigation has been conducted into the leaching of Crocker Well ore concentrates and the recovery of uranium and thorium from the leach liquor. Approximately 90% of the uranium and 80% of the thorium can be extracted from the concentrates by hot...-

Ifould Lake. Progress and final reports for the period 29/11/1974 to 4/8/1976.
10 reverse circulation holes were drilled, totalling 311 m. Surface radiometric effects were attributed to groundwater Ra and/or Rn, or to evaporitic concentrations of uranium daughter products. Results from drilling and from track etch (alpha)...-
