Abrégé
The present invention provides a process for the production of a uranium trioxide yellowcake from a uranium peroxide precipitate, the peroxide precipitate being in the form of a low solids content, uranium rich feed slurry, the process including the stages of: a. thickening the feed slurry to produce a thickener underflow with a solids content in the range of 15 to 50% w/w and a thickener overflow; b. dewatering the thickener underflow to produce a solids cake with a solids content of at least 50% w/w and a dewater overflow; and c. calcining the solids cake at a temperature in the range of 450° C. to 480° C. to produce a calcined uranium trioxide yellowcake.

Abrégé
The present invention provides apparatus for the production of a uranium yellowcake from a uranium peroxide precipitate, the peroxide precipitate being in the form of a low solids content, uranium rich feed slurry, the apparatus including: a. a thickener for thickening the feed slurry to produce a thickener underflow with a solids content in the range of 15 to 50% w/w and a thickener overflow; b. a means for dewatering the thickener underflow to produce a solids cake with a solids content of at least 50% w/w and a dewater overflow; and c. an indirectly heated kiln for heating the solids cake at a temperature suitable to produce either a calcined uranium trioxide yellowcake or a dried uranium peroxide yellowcake.

Abrégé
A process for the drying of yellowcake, the yellowcake initially being in the form of a low solids content, uranium rich feed slurry, the process including the stages of : a. dewatering the feed slurry to produce a first dewatered solids cake with a solids content higher than the feed slurry; b. re-slurrying the first dewatered solids cake with sufficient water to dissolve at least some impurities and to produce an intermediate slurry with a solids content lower than the first dewatered solids cake; c. dewatering the intermediate slurry to produce a second dewatered solids cake with a solids content higher than the feed slurry; and d. drying the second dewatered solids cake to produce dried yellowcake.
