Talvivaara Planning Uranium Recovery

Talvivaara Mining Co., which recovers nickel, zinc and copper from bio heap leach process solutions at its operations in eastern Finland, has announced plans to recover small amounts of uranium that also leach out of its ores. Uranium grade in the Talvivaara ore averages 15 to 20 ppm, and uranium concentration in the heap leach solutions is low, at about 25 mg/l. However, Talvivaara reports that it has developed a solvent extraction process that can economically extract about 350 mt/y of U3O8 from these solutions. In the company’s current production process, extremely small concentrations of uranium are deposited in an engineered gypsum pond intended for process precipitations.
