High quality and thick size ammonium diuranate prepared by fluidization technique

Technical Report:

Abstract

The process of preparing ammonium diuranate with high quality and coarse grain is presented, which was precipitated by fluidization technique in sulfuric acid-ammonium sulfate or sulfuric acid-chloride solution system. In sulfuric acid-ammonium sulfate solution system, the product produced by conventional agitation-precipitation method contains 63.18% of U and 13.3% of SO{sub 2}{sup 2-}, and the percentage of particles with diameter {>=} 40 {mu}m is 33.91%. Under the optimum conditions with fluidization technique the values are 69.94%, 3.7% and 75.87% respectively. In the sulfuric acid-chloride solution system, the product obtained by agitation method in factory contains 58% of U and 5% of Cl{sup -}, and the percentage of particles size {>=}40 {mu}m is 1.6%. By using fluidization method the values are 68%, 0.22% and 41.46% respectively. The diameter and height of testing fluidized-bed are 400 mm and 3200 mm. It has a simple structure and adaptability for concentration variation of solution. The operation is easy and steady and it will have a broad application in the industry.
