Description: This report describes tests conducted at Pacific Northwest National Laboratory to investigate selective leaching of iron from Hanford tank sludges. As Fe represents a significant fraction of the sludge mass, its removal would reduce the mass of the material needed to be handled as high-level waste. Iron leaching can be viewed as an enhancement to the baseline method of caustic leaching, which primarily removes Al, P, and Cr. The U.S. Department of Energy funded the work through the Tanks Focus Area (TFA;EM-50).
