Cyanide Removal From Coke Making and Blast Furnace Wastewaters

Initial two-phase batch extraction tests using CCU as the amine solvent indicated an average 3.5/1 amine/ferrocyanide stoichiometry. Dispersion of the amine in ferrocyanide solution produced a finely dispersed wax. Subsequent addition of iron produced a floatable amine-iron-cyanide precipitate. Minimum iron addition was found to be 250 mg/l.
