| Abstract: | As a new production technique of yellow cake,resorption with loaded resin elution with acid ammonium nitrate precipitation in two steps is studied.The results show that the produced yellow cake by the new production technique has better performance of settlement,filtration and dehydration.Each index of yellow cake accords with the first grade level issued by CNNC without washing,uranium and water content are 70% and 25%,respectively. |
