Uranium Adsorption from Leach Slurries

Uranium Adsorption from Leach Slurries

To promote thickening and clarification in uranium milling, a char adsorbent is added to the slurry of ore and cyanide leach solution, and then screened from the slurry. Di-2-ethylhexyl pyrophosphate is placed on the surface of the char to bond with uranium. A full description of the process is pres...

Zusammenfassung:To promote thickening and clarification in uranium milling, a char adsorbent is added to the slurry of ore and cyanide leach solution, and then screened from the slurry. Di-2-ethylhexyl pyrophosphate is placed on the surface of the char to bond with uranium. A full description of the process is presented, including graphs and a flowsheet diagram.
