heal.abstract	The classical slope analysis and a statistical technique were used in order to determine the iron complexes formed in the organic phase during the extraction of Fe(III) from Fe-Ni-Co sulfate solutions with Di-(2-ethylhexyl) phosphoric acid (D2EHPA) in kerosene. Equilibrium constants for the extraction based on these complexes were also calculated. The complexes determined were of the general form (Fe(OH)//3// minus //nR//n does not equal sHR)//x, where n varied between 1 and 2. 5 and s between 0 and 3, and both were found to be decreasing as the iron loading in the organic phase increased. Values of 1, 2 and 3 were generally found for x, indicating that the complexes were monomers, dimers and trimers.	en
