Chalcopyrite is closely related to that of zinc blende ZnS (sphalerite). The unit cell is twice as large, reflecting an alternation of Cu and Fe ions replacing Zn ions in adjacent cells. In contrast to the pyrite structure chalcopyrite has single S sulfide anions rather than disulfide pairs. Another difference is that the iron cation is not diamagnetic low spin Fe(II) as in pyrite. Copper metal can be extracted from the roasting of chalcopyrite, as shown in the following reaction: Although if roasted partially it produces and . Chalcopyrite Chalcopyrite ( ) is a copper iron sulfide mineral that crystallizes in
Central Ore Mountains Central Ore Mountains The Central or Middle Ore Mountains ( or "Mittelerzgebirge") is a natural region that forms the central-western part of the Ore Mountains in the German federal state of Saxony. It is part of the overarching unit, the Saxon Highlands and Uplands. It forms the eastern part of the former major units, the Lower Western Ore Mountains ("Unteres Westerzgebirge", 423) and Upper Western Ore Mountains ("Oberes Westerzgebirge", 421) and is separated from the Eastern Ore Mountains in the east by the (included) valley of the Flöha, and from the Western Ore Mountains in the west by the (excluded)
