Description

In the processing of uranium ores, uranium is recovered from mill leach solutions and is transported to a processing plant. This step allows obtaining an uranium concentrate by precipitation. After drying, a solid uranium concentrate is produced (called "yellow cake" due to its color and its doughy texture at the end of the procedure), containing around 75% uranium. The "yellow cake" is packaged and put into barrels, then sent to conversion facilities for further chemical processing.
