Separation and determination of uranium and thorium in

The separated zircon assemblages were examined by a polarizing petrographic microscope and X ray diffraction techniques and found that it contained more than 75 pure zircon Thereafter uranium and thorium concentrations in zircon were measured by NAA and revealed that zircon contained 94 141 ppm uranium and 127 506 ppm thorium.

invented incandescent mantles.Monazite sand was quickly adopted as the thorium source and became the foundation of the rareearth industry.Monazite is a reddish brown phosphate mineral containing rare earth metals It occurs usually Due to the alpha decay of thorium and uranium monazite contains a significant and contain other heavy minerals of commercial interest such as zircon and ilmenite The
