Abstract
Abstract —Data from the Chuktukon, Tomtor (Russia), and Morro dos Seis Lagos (Brazil) mineral deposits demonstrate that the mineral potential of laterite produced by weathering of carbonatites can be extended with Fe, Mn, Ti, and V, which are commonly beyond the conventional ore production. Several previously unknown factors have been revealed, which control the mineral potential of laterite: reduction of weathering products, composition and ore contents of carbonatite, lateral and vertical migration of elements, as well as liquid fractionation of colloids in upper zones of weathering profiles. The reported study provides additional arguments for the idea that laterite derived from carbonatites stores unique multicomponent mineralization of heavy lanthanides, Y, Sc, Fe, Mn, Ti, V, Sr, Ba, Al, and Ga, besides the common target commodities of Nb, La, Ce, and P.
