2 天前  Zircon Processing: This example analyzes a continuous hydrometallurgical process for the extraction, separation and recovery of zirconium, uranium and hafnium from zircon sand. The process features alkali fusion, leaching, precipitation and solvent extraction in counter-current mode for the separation and recovery of the three valuable metals.

Determination of thorium and uranium in mineral

1994-6-10  Thorium and uranium can be determined by ion chromatography using a C 18 reversed-phase column and a complexing eluent of hydroxyisobutyric acid followed by post-column derivatization with Arsenazo III and detection at 658 nm. A number of sample dissolution and clean-up procedures were evaluated in order to permit the application of the chromatographic method to the analysis of mineral
