of world uranium resources. Ore bodies of this type are commonly low to medium grade ( % U 3O 8). The United States has large resources in sandstone deposits and most of its uranium production has been from these deposits, recently by in situ leach (ISL) mining. Other large sandstone deposits occur in Texas, Colorado
The current study aimed to extract uranium from Egyptian ores using native strains of actinomycetes. Two types of rocks and one ore sample were collected from westcentral Sinai, Egypt. Major oxides of the samples and fourteen heavy metals, including uranium, were determined.
