Cobalt-rich manganese crusts and crust-concretion formations from the guyots of the Pacific Ocean were found to be the natural highly selective sorbents of rare-earth cations Ce3+, Y3+, La3+. Ion exchange capacity of ore minerals — vernadite, Fe-vernadite and Mn-ferroxyhyte — increases in the following sequence La3+<Y3+<Co2+<Ce3+ and averages from 1.67 (La3+) to 2.84 (Се3+) meq/g, which is quite high values among natural mineral ion exchangers. Ore minerals of crusts exhibit higher selectivity to Се3+ cation compared to Y3+ и La3+. The age of ore minerals does not affect their sorption with respect to rare earth element cations.
