Extraction et traitement du minerai d'uranium au Niger

From ore to yellowcake: purifying and concentrating uranium . The uranium extracted from an open-pit or underground mine must be separated from the waste rock and rid of as many impurities as possible. To avoid needlessly transporting many tons of ore over long distances, this concentration operation is carried out in the immediate vicinity of mining sites.

Uranium processing - Canadian Nuclear Association

After mining, uranium ore is transported to a nearby mill for processing. 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 rock.

Why is it so expensive to purify plutonium or enrich uranium?

The starting point is "yellowcake" uranium ore, which is dissolved in nitiric acid, yielding uranyl nitrate. This is purified, then treated with ammonia, yielding ammonium diuranate. That is converted to uranium dioxide by reduction with hydrogen.
