Nickel and cobalt are separated from MHP by selective leaching, solvent extraction and ion exchange. The selective leaching method has been adapted to separate nickel from cobalt and manganese with the help of selective oxidation . One method of refining MHP is an ammonium-carbonate leach employed at the Queensland Nickel and …Web

this circuit is treated for cobalt recovery. The most common cobalt recovery route involves the sequential precipitation of iron, aluminium and manganese using lime at pH 3.5, followed by cobalt precipitation at pH 8.5. Magnesia, despite being far more expensive, is widely used for cobalt precipitation in preference to lime, owing to itsWeb

Concerning the global flow chart for the production of cobalt chemicals, a major uncertainty stems from cobalt production volumes that originate from ores mined by artisanal miners. National agencies have limited possibilities to allow for a consistent declaration of these ores and thus, volumes may in fact be significantly higher or lower.Web
