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
Ore Mountains one overarching unit, the Saxon Highlands and Uplands. In addition, its internal divisions were changed. Former major unit 420 was grouped with the western part of major units 421 and 423 to form a new major unit, the Western Ore Mountains ("Westerzgebirge"), the eastern part of major units 421 and 423 became the Central Ore Mountains ("Mittelerzgebirge") and major units 422 and 424 became the Eastern Ore Mountains ("Osterzgebirge"). The current division therefore looks as follows: The geographic unit of the Southern Slopes of the Ore Mountains remains unchanged under the title of Southern Ore Mountains ("Süderzgebirge"). The climate of
