Abstract

The Roessing uranium deposit is located in the Namib desert about 40 miles northeast of Swakopmund, South West Africa.The uranium mineralization is associated with a syntectic alaskite that shows wide textural variations ranging from aplitic, granitic, to pegmatitic and that evidences concordant, discordant, and replacement relationships to the heavily folded gneisses, schists, marbles, and limestones of the Khan and Roessing Formations.The uranium-bearing minerals are mainly uraninite and its alteration products with minor betafite. The winning of uranium will be effected by a sulfuric acid leach followed by ion exchange, solvent, extraction, and ammonia precipitation.
