Lesson plan
Yellowcake
Yellowcake, also known as urania, is a type of powdered uranium concentrate obtained from leach solutions, representing an intermediate step in the processing of uranium ores. This material is produced after uranium mining but before either fuel fabrication or uranium enrichment. Yellowcake concentrates are created through various extraction and refining methods that vary depending on the ore types. The production involves milling and chemical processing of uranium ore, resulting in a coarse powder that is insoluble in water and has a pungent odor. Yellowcake typically contains about 80% uranium oxide and melts at approximately 2880 °C.
