英文摘要	Cataclastic rocks of Abu Rushied area (South Eastern Desert, Egypt) characterized by the presence of niobium, tantalum, zirconium minerals as well as uranium-thorium minerals. Physical upgrading process was applied using gravity and magnetic separation techniques to concentrate these economic minerals mainly to obtain the magnetic niobium concentrate at 0.2-0.5 ampere, beside the non-magnetic Zr and U at 1.5 ampere. The chemical processing upon niobium concentrate was performed using NH4F roasting process at 250 degrees C followed by selective precipitation of Nb as Nb-sulfide. An alkaline fusion using NaOH was applied upon zirconium concentrate at the optimum conditions of: zircon concentrate/NaOH mass ratio 1/2, fusion temperature of 650 degrees C and 2.5h fusion time followed by selective precipitation of Zr as Zr-tartrate. Finally, two flowsheets were drawn summarizing the whole recovery processes.
