Uranium Mining and Extraction from Ore

Uranium Extraction. Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.

uranium heap leaching process

Uranium Heap Leaching. In some cases, uranium is extracted from low-grade ore by heap leaching. This may be done if the uranium contents is too low for the ore to be economically processed in a uranium mill. The crushed ore is placed on a leaching pad with a liner.

Iran’s uranium gambit is a dangerous negotiating tactic

Jul 13, 2021 On July 6, the International Atomic Energy Agency (IAEA) reported that Iran was moving ahead with manufacturing “uranium metal enriched to 20 percent U-235 [uranium’s most fissile isotope],” the latest in a series of steps violating Iran’s commitments under the Joint Comprehensive Plan of Action (JCPOA). While Tehran maintains that there is little for the international community to be
