The phase and chemical compositions of the mineral chalcopyrite from the sulfide footwall vein in La Cantera (Zacatecas, Mexico) is examined by powder X‐ray diffraction, energy dispersive X‐ray spectroscopy, and chemical ICP‐OES analyses. The influence of the detected impurities on the thermoelectric parameters (i.e. thermopower, electrical and thermal conductivities) is discussed. Thermoelectric figure of merit, ZT , of the studied natural minerals is found to be of the same order of magnitude (ca. 10 –3 ) as reported for CuFeS 2 synthesized in the laboratory.
