Magnesium diuranate (MgU2O7) is a compound of uranium. It is known in the uranium refining industry as "MDU" and forms the major part of some yellowcake mixtures. Yellowcakes are an intermediate product in the uranium refining process.

To produce this form of yellowcake, crushed ore is mixed with hot water to a 58% solids sodium chloride aqueous phase after which the barren solvent is recycled. The average efficiency of the SX circuit is 99.9%. The high-grade “pregnant” strip solution from SX goes to the next stage where magnesia slurry is added to precipitate magnesium diuranate. The yellow cake precipitate is then thickened, dried, re-crushed and packed into industry standard 220 litre steel drums for shipment to customers.

As with all yellowcake process the selection of this end product is dependent on the properties of the ore to be processed. The point of using magnesia is that you
