takes place by stirring in order to promote the dispersion of one phase within the other and, withthis, the selective transfer of the metal from the aqueous solution to theorganic phase. This transfer occurs by chemical bond between the metalion and the extractant, which results in the formation of an organometallic compound. The phase disengagement occurs by gravitationalsettling, in which the coalescence of the droplets from the dispersedphase and the decantation of the denser solution occurs [1].
