Chalcopyrite ( / ˌkælkəˈpaɪˌraɪt, - koʊ -/ [7] [8] KAL-kə-PY-ryte, -⁠koh-) is a copper iron sulfide mineral and the most abundant copper ore mineral. It has the chemical formula CuFeS 2 and crystallizes in the tetragonal system. It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale. Sphalerite is an ore—a mineral of economic value—that was once mined in southeastern Kansas for its zinc content. It is also called zinc blende, blende, blackjack, and mock lead. Sphalerite crystals are usually shaped like triangular pyramids, with three sides and a base. Because it has good cleavage in six directions, sphalerite will break ...5 matching records for this search. Sphalerite. Skinner B J. American Mineralogist 46 (1961) 1399-1411.

The iron content of sphalerite influences several physical properties, such as microhardness, because it influences the reticular parameter “a” of ...Sphalerite. While most fluorescent specimens of the mineral exhibit an orange fluorescence, sphalerite can fluoresce in a rainbow of colors. A zinc sulfide, sphalerite is the most common and most important zinc ore in world. Sphalerite typically occurs as well-formed crystals in a variety of sizes.
