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
Thicketty Mountain Ore Pits (38CK74) Thicketty Mountain Ore Pits (38CK74) Thicketty Mountain Ore Pits (38CK74) is a historic archaeological site located near Shady Grove Church, Cherokee County, South Carolina. The site includes iron ore pits associated with the South Carolina Manufacturing Company, a major iron manufacturing company that operated in Spartanburg County between about 1825 and about 1850. The iron ore pits or surface mines cover several forested acres along a gently sloping ridge and are generally depressions about two to three meters deep and about five to ten meters across. The pits were last operational in the 1850s. It was listed in the National
