Abstract
Developments in uranium ore processing technology since the AAEC Symposium on Uranium Processing in July 1972 are reviewed. The main developments include the use of:
- autogenous or semi-autogenous grinding,
- benefication techniques such as radiometric sorting, flotation, magnetic and gravity separation,
- strong acid and ferric bacterial leaching processes,
- solution mining and heap leaching operations
- horizontal belt filters for solid-liquid separation,
- continuous ion exchange processes for use with solutions containing up to 8wt % solids,
- hydrogen peroxide and ammonia for the precipitation of uranium to improve product yield and purity, and
- the recovery of by-product uranium from the manufacture of phosphoric acid and copper processing operations.
