Yellow Cake, the transformation of uranium ore | Orano
Leach it, oxidize it and decant it before clarifying it. Add solvents, then precipitate this mixture. The result is a yellow solution called yellowcake. Put it in an 800°C oven and bake until it is a grey powder with a uranium content of 85%. Carefully place in drums before sending it to the conversion plant of your choice.

Uranium Recovery (Extraction) Methods | NRC.gov
Alternatively, uranium may be recovered from the ore using a heap leach process. In the heap leach process, the ore is placed on a engineered barrier and sprayed with acid. The uranium dissolves into solution and is collected at the engineered barrier. The solution undergoes additional chemical processing to produce "yellowcake".
