摘要： A process for extracting uranium from an acidic uranium, chloride, iron and sulphate containing solution, including the steps: a. contacting the solution with an organic phase containing a trialkylphosphine oxide to form a uranium loaded organic phase; b. scrubbing the uranium loaded organic phase to remove any impurities and form a scrubbed organic phase; c. stripping the scrubbed organic phase with an acidic sulphate solution to produce an aqueous uranium strip solution; and precipitating a uranium product from the aqueous uranium strip solution.
