Liquid-liquid separation of Cd (II) from Cu-sulfide cake prepared from sulfate solution of Abu-Thor ore material, Southwestern, Sinai, Egypt

The present work is concerned with the subsequent liquid-liquid separation of Cu, Zn, and Cd compounds from Cu- sulfide cake prepared from the sulfate solution of Abu-Thor Gibbsite-bearing shale ore material. This ore was found assaying 0.014% of Cd, 0.5% of Cu, and 0.55% of Zn as the elements of interest, by using 25% of H₂SO₄ solution at a solid/liquid ratio of 1/3 reaction time of 90 min at a...
