The extraction of non-ferrous metal ions (Co, Ni, Cu, Al) from chloride solutions with poly(propylene glycol) 425 was studied. The values of the distribution coefficients and the degree of metal ions extraction are determined in the system under study. The mechanism of metal extraction in the poly(propylene glycol) 425 – sodium chloride– water extraction system in the presence of KSCN is described. The possibility of selective extraction of Co (II), Ni (II), Cu (II) and Al (III) from chloride solutions with poly(propylene glycol) 425 in the presence of KSCN is shown.
