text: Since nodules are built up of nanometre-scale manganese oxides and iron oxyhydroxides that are epitaxially intergrown (crystallographically aligned FeOOH and MnO 2 laminae), it is not possible to separate and enrich the metals of interest from the other nodule components by conventional beneficiation methods, such as flotation, density separation or magnetic separation97,98.
