Abstract
The present study is concerned with the feasibility of using organic solvent, Alamine336 in kerosene to extract U from sulfate leach liquor of Abu-Hamata sandy clay stone ore sample. The prepared sulfate leach liquor assays 0.45g/L of U with achieved leaching efficiency of 98.9%. The obtained results indicate that U extraction efficiency depends mainly on Alamine 336 concentration, strongly influenced by pH value, contact time and the organic / aqueous (O/A) ratio.
Uranium in the organic phase was stripped using a solution of 1M NaCl acidified with 0.2M H2SO4 with an achieved stripping efficiency of 93.9% at A/O ratio of 1/1 and shaking time of 5min. Not less than 99% of U in the obtained U rich strip solution was directly precipitated using H2O2 solution to produce the final pure product of U3O8.
