Yellowcake

Yellowcake – U3O8. Yellowcake, chemically U3O8, is a uranium concentrate powder recovered from leach solutions. Yellowcake is an intermediate step in processing uranium ores and nuclear fuel production. Typically, yellowcake can be obtained through the conventional milling and chemical processing of uranium ore, forming a coarse powder.

The milling process for uranium is similar to that used for other metals such as copper, gold or nickel. The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits. After crushing, the ore is treated with acid in large tanks to separate the uranium from other minerals in the host rock.
