ABSTRACT:
A process for the removal of cyanides from contaminated oily solid waste performed by utilizing a single processing zone wherein multiple processing steps are carried out to remove contaminants. The steps include loading a contaminated oily solid waste into a zone where the solid is reduced in size, adjusting the pH of the oily solid waste, dewatering or deoiling the oily solid waste and drying the resulting solid, extracting the resulting dried solid with organic solvent, and further drying the extracted solid to remove residual moisture, cyanide, solvent, and volatile organics.
