Fluid Bed Precipitation

"U" Fluid Bed Precipitation

Adelaide Control Engineering can provide fully commissioned plant for the continuous fluid bed precipitation of yellowcake. Available as either modular units within shipping containers for pilot or demonstration plants or as larger plant depending upon required rate of production.



The figure below shows the difference between the crystals produced from Fluid Bed Precipitation and Tank Precipitation. Notice that crystals produced in the fluid bed are three times the size and are more spherical when compared to the traditional tank precipitation crystals.

Areva Patented Process.

Fluid Bed Precipitation produces  larger particles with almost no fines or small particles.

Fluid bed precipitation works with any precipitation method (e.g. ammonia, hydrogen peroxide, etc.) to produce superior uranium products.

Advantages over Standard Tank Precipitation Methods 

  • Lower cost of production and maintenance (up to 25%)
  • Increased recovery of uranium (up to 0.5% of plant capacity)
  • Increased uranium content of calcined product (up to 3%)
  • Reduced fines, less dust and lower risks to operators
  • Increased calcined product bulk density (up to 2.8-3.2 kg/L)
  • Reduced transport  costs (up to 25% with U3O8)
  • Lower impurities and penalty costs
  • Larger particle size (D50: ? µm vs 15 µm)
  • Improved dewatering reduces calcining costs or allows increased throughput (up to 40%)
  • Improved flowability and solids handling
