Upgrading of the Crude Yellow Cake to a Highly Purified Form using Tris (2-ethylhexyl) Phosphate in Presence of EDTA or CDTA

Article English OPEN
Ali, Amr Hamdy; Eliwa, Ahmed Atef; Hagag, Mohammed Sobbhy;

Upgrading crude yellow cake was done by 0.05 M Tris 2-ethylhexyl Phosphate / kerosene from 5 M nitrate solution.  More than 98 % of uranium extracted after 5 stages of contact, shaking time 5 minutes and volume phase ratio 1/1. Uranium stripping efficiency reached ... View more
