Leaching aluminum from calcined kaolinitic clay with nitric acid. Report of investigations/1983

Technical Report ·
OSTI ID:6852054
Prior work by the Bureau of Mines demonstrated a feed preparation method that eliminates the formation of slime during leaching of calcined kaolinitic clay and makes leached residues fast settling and easy to filter. Nitric acid leaching rates determined for calcined kaolinitic clay prepared by this method were found to correspond to a zero-order reaction model for both batch and continuous, stirred-tank leaching. A rate constant of 0.136/min was determined. Separation of solid residues from the reacted slurry was examined, and filtration rates were determined.
