Mineralogical and radiological studies on some Paleozoic yellow ochre deposits in Southwestern Sinai, Egypt.

Yellow ochre is the basic material used in the manufacture of yellow oxide (a commercial product). Yellow ochre samples were taken from three different formations in southwestern Sinai: Abu Hamata, Um Bogma, and Abu Zarab. Yellow ochre occasionally exists in Abu Hamata Formation particularly in El Ferah area, associated with Fe-Mn ore in Wadi El Sahu (Um Bogma Formation) and in Himayer area (Abu Zarab Formation).

Radioactive Attenuation Using Different Types of Natural Rocks.

Humans benefit from nuclear technology, but it also generates nuclear radiation that is bad for both the environment and human health. The serious issue of radiation leakage affects many technological applications. Shielding is required to protect both users and the environment from negative side effects.

Bioleaching Studies of Uranium in a Rock Sample from Sinai Using Some Native Streptomyces and Aspergillus Species.

Sinai's important geographical and strategic position is attracting researchers to explore opportunities to maximize exploitation of its treasures, especially in the area of sustainable development. One of the fields of exploitation is extracting valuable metals from low-grade ores using green technologies. In this study, we examined the possibility of microbial leaching of uranium (U) from a rock sample collected from Wadi Naseib, Sinai, Egypt.
