1,5-Diphenylthiocarbazone-Modified Amberlite XAD-7: A Chelating Collector for Upgrading Uranium Concentrate Produced from G. Gattar Pilot Plant, North Eastern Desert, Egypt

Abstract

Crude uranium concentrate (30–35.8% U) from G. Gattar pilot plant, North Eastern Desert, Egypt, produced by acid heap percolation leaching, was upgraded by 1,5-diphenylthiocarbazone-modified Amberlite XAD-7 (H₂Dz-XAD-7). The modified resin was characterized by EDAX, SEM, CHNSO analysis, and FTIR. The purified cake was characterized by XRD, EDAX, and ICP-OES techniques.
