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 animals that have been found at higher altitudes of the Ore mountains are otherwise only known from more distant places in the Sudeten mountains or the Alps. After conditions improved, once displaced species such as Eagle owls and Black storks have returned in the early 21st century. The German part of the Ore Mountains is one of the major business locations in Saxony. The region has a high density of industrial operations. Since 2000, the number of industrial workers has risen against the Germany-wide trend by about 20 percent. Typical of the Ore Mountains are mainly small, often owner-managed, businesses.
