| 摘要 |
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.
