Natural U3O8
Uranium division of Ulba Metallurgical Plant developed and introduced a method of processing Uranium chemical concentrates produced in the Kazakhstan mines.
Upon the Customer's request, Uranium production is capable to produce both conventional technical U3O8, which undergoes additional preparation for fluorination followed by further treatment by the processors, and U3O8, which is ready for direct luorination by the processors.
The Consumers of U3O8 produced at Ulba Metallurgical Plant are the leading conversion facilities of Russia, France, Canada and USA.
Natural Uranium currently mined in Kazakhstan is mostly processed at Ulba Metallurgical Plant.
