Depletion and enrichment of primary haloes: their ...

Aug 01, 2003 · The model of the primary halo that was created in the 1930s has not fundamentally changed. The primary halo of an ore deposit (ore body) is considered an environment of enrichment of oreforming and associated elements as a result of ore genesis. However, extensive multielement geochemical data show that the primary halo, like the positive anomaly, is only part of a complexly .

Ore sorting: Efficiently optimise the treatment of ores in ...

There are many ways of improving recovery processes for a wide variety of ores using sorting equipment. At STEINERT we always take the same approach: sorting waste rock and ore with low concentrations out from the process at an early stage to save energy and resources and to unlock more enriched ore more effectively.

Uranium Enrichment |

Dec 02, 2020 · Gas Centrifuge. Gas centrifuge enrichment is the current process by which commercial enrichment is being performed in the United States. UF 6 gas is placed in a gas centrifuge cylinder and rotated at a high speed. This rotation creates a strong centrifugal force so that the heavier gas molecules (UF 6 containing U 238 atoms) move towards the outside of the cylinder.
