1) Purifying: the ability to process any type of uranium ore The Malvési (Aude) site purifies uranium concentrates from mines around the world and converts them into uranium tetrafluoride (UF 4).; The site provides thermal denitration services using an innovative and unique process worldwide, Isoflash (UO3), which eliminates chemical product input, in particular ammonia.

The nuclear fuel cycle
The uranium dissolves into the groundwater, which is pumped out of the reservoir and processed at a uranium mill. Another similar process, heap leaching, involves spraying an acidic liquid solution onto piles of crushed uranium ore. The solution drains down through the crushed ore and leaches uranium out of the rock, which is recovered from ...
