UO2 nanoparticles synthesis from leaching solutions on the hematite support

Zygmunt Sadowski, Aleksandra Sklodowska

Abstract


In the present studies the bacterial leaching process is used to extract uranium from the uranium mining wastes. The bioleaching process is environment friendly and gives the extraction yield of over 90%. The bioleaching solutions were obtained from the waste materials located at different places at Lover Silesia (Kowary, Grzmiąca, Kopaniec). Among various templates the hematite Fe2O3 nanoparticles are most useful. Interactions uranium ions with synthesized nanoparticles of hematite, magnesite, and iron were examined.
