A gravitational isotope is that fraction or constituent of a sample of an element having the same inertial mass but a different gravitational mass than the balance of the sample. Such isotopes may be either lighter or heavier (gravitationally) than the normal composition but will have approximately the same inertial mass as the normal composition.

uranium ore gravity separations

Gravity separation and Ore Beneficiation Gravity separation is the oldest known ore beneficiation technique and is practiced extensively in 'Nature'. Earliest recorded human use of gravity separation was recovery of gold by panning from the Upper Nile by ancient Egyptians, dating back to 1900 BCE.

Collectively, these provided much impetus to develop mature technologies to recover nickel from laterite ores. Hydrometallurgical processes, as the effective technologies, are preferred to extract the nickel from limonitic laterite which is a principal nickel-bearing ore [6,7,8].].

Isotope Separation by Ion Cyclotron Resonance Acceleration EPISODE 2 The Calutron The world did not lack methods for separating isotopes when it discovered the possible utility of a kilogram of uranium-235 U-235 Known techniques pursued simultaneously in Germany and the United States included ultra-centrifugation diffusion across thermal or osmotic pressure barriers and deflection in electric

J. Hermann, D. Rubatto, in Treatise on Geochemistry (Second Edition), 20144.9.7.2 U–Pb Dating of Zircon Zircon is the most commonly used accessory mineral for UHP geochronology. Monazite is not often reported in UHP rocks (see Section 4.9.7.3), rutile is commonly too poor in U, and titanite is a retrograde phase in most bulk compositions and also poor in U. Geochronology of UHP terranes

Unlike many industrial minerals that find direct use after mining and limited beneficiation, the ore minerals, in general, must be reduced to metal by complex processing. Modern mining and mineral extraction procedures are tending towards greater use of chemical and bacterial leaching methods for suitable ores, such as in-situ extraction of some uranium deposits, and heap leaching of some gold

The different radionuclides in the 238 U, 235 U and 232 Th decay chains may be separated from the REE, and each other, during beneficiation and processing. The point at which separation occurs is determined by the chemistry of the elements and their physicochemical associations in the ore.
