Aluminum Sulfate Leach Solution Extracting Iron
The iron concentration in the raffinate varied between 0.14 g/l without oxidant and 0.004 g/l after oxidation indicating that the presence of ferrous iron has a marked detrimental effect on overall iron extraction. Hydrogen peroxide was added to all subsequent portions of leach solution prior to extraction studies.
