摘要：

results of experimental studies of the sorption properties of ferromanganese crusts on the Kocebu Guyot relative to rare-earth metal (REM) cations are presented. It is established that the crusts are a natural, highly selective sorbent of REM cations. The REM cations are adsorbed on ore minerals (Fevernadite, vernadite, Mn-feroxyhyte, and goethite). The crusts are characterized by a high exchange capacity (1.67-3.28 mg-equiv/g), which increases in the series: Lu < Gd < Dy < La, Sm < Nd < Y < Eu << Ce. The REM cations are adsorbed by the ion-exchange equivalent mechanism-in the case of Ce3+ cations, according to the superequivalent mechanism with respect to cations of the exchange complex of ore minerals-Na+, K+, Ca2+, Mg2+, Mn2+, and Ni2+, which contribute 95-98% to the total capacity of minerals.
