Abstract

Chemical processing of the ferruginous gibbsite-bearing shale ore material of southwestern (SW) Sinai , has been studied for the recovery of U, REEs and B together with the possible associated Cu, Zn and Al contents. A technological sample assaying 0.04 % U, 0.2143 % REEs, 1%Zn, 2.3% Cu, 38% Al2O3 and 0.1% B has thus been collected. U, REEs, Cu, Zn and Al have been leached upon their combined sulfate leach liquor. Under the optimum conditions, leaching efficiencies of about 100% for U, 88 % for REEs, 68.57 % for Cu, 66.52 % for Zn and 37.51 % for Al have been achieved. The work was then shifted for the recovery of boron from the residue left behind .The latter was accomplished by roasting with sodium hydroxide to achieve 95% leaching efficiency. From the two adequately obtained leach liquors, marketable products have conveniently been prepared.
