Abstract
The structural location of Cu in lithiophorite from a banded Mn ore from the Ivory Coast has been determined by extended X-ray absorption fine structure (EXAFS) measurements. Cu atoms are located within the hydrargillite [Al(OH)3] sheet of lithiophorite and substitute for Al or Li. The Cu location is the same as that of Ni and differs from that of Co, which is in edge-sharing octahedra within sheets possessing a buserite-like structure. High-resolution transmission electron microscopy confirms that the major phase is lithiophorite together with minor hollandite. -Authors
