· Pink quartz in the basement, which occurs as veins and breccias in spatial association with uranium mineralization, is characterized by elevated, homogeneously distributed radiationinduced defects, suggesting its crystallization from uraniumbearing fluids most likely linked to the main mineralization event. Smoky quartz in veins and cavities often exhibits .
· The QuartzPebble Conglomerate deposits can be very large varying between 12 and 375 million pounds U3O8 and most of the mineralization is in the form of black uraninite which is unusual for secondary deposits. Mining and processing of uranium ore: The three mining methods; open pitting, underground mining and In Situ Leach or ISL. The ...
· The precedent for this approach is set by uranium exploration history: Exploration occurred in spurts stimulated by demand beyond the capability of known deposits and distinguished by recognition of new types of larger, richer deposits which could supply the demand. Stagnation in the 1960's and 1970's of the discovery rate for "conventional" .
· The quartz mineral has a very high resistance to chemical and mechanical weathering and such durability makes it the most dominant mineral found on mountaintops. Moreover, it is the major constituent of rivers, desert sand, and the beach. It is not only durable, but it is also ubiquitous as well.

· Uranium and numerous other rare elements are mined in Butana, Red Sea, West and South Kordofan, and Darfur pit copper. Kaoline is found in the southern parts of the Nile River State and some parts of Khartoum. Gypsum reserve was identified in Mount Sagomhas and the Beraat area while graphite is in the Blue Nile.
· Surface complexation models (SCMs) are widely utilized as a tool to study the mobility of radionuclide to the environment. In this study, two SCMs, electrostatic (ES) and nonelectrostatic (NES) models are employed in order to simulate the sorption behavior of U(VI) on quartz in the absence of Mg, Ca, and Sr and ES model in the presence of alkaline earth metals.

Classifiion of Uranium Deposits IF. J. Dahlkamp A listing of the recognized types of uranium mineralization shows nineteen determin able types out of which only six can be classified as of economic significance at present: Oligomictic quartz pebble conglomerates, sandstone types, calcretes, intra intrusive types, hydrothermal veins, veinlike types. The different types can be .
In this work, the determination of uranium in powdered highpurity quartz samples was studied using a simplified fission track procedure in which ∼ g each of sample and a fission track detector (synthetic quartz glass plate, uranium impurity ∼ ppb) were loaded in a polyethylene capsule and irradiated with a thermal neutron flux of ∼ 1017 cm2. An easy .
