Copper(II) chloride is used as a catalyst in a variety of processes that produce chlorine by oxychlorination. The Deacon process takes place at about 400 to 450 °C in the presence of a copper chloride: [8] 4 HCl + O 2 → 2 Cl 2 + 2 H 2 O. Copper(II) chloride catalyzes the chlorination in the production of vinyl chloride and dichloromethane. [8]
IR absorption spectrum of copper (I) chloride. Copper (I) chloride, commonly called cuprous chloride, is the lower chloride of copper, with the formula CuCl. The substance is a white solid sparingly soluble in water, but very soluble in concentrated hydrochloric acid. Impure samples appear green due to the presence of copper (II) chloride (CuCl 2).

In the US, more copper is recovered and put back into service from recycled material than is derived from newly mined ore. Copper's recycle value is so great that premium-grade scrap normally has at least 95% of the value of primary metal from newly mined ore. [79] In Europe, about 50% of copper demand comes from recycling (as of 2016). [80]
References. [2][3][4][5][6] 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.
Mineral Park was a mining town, now a ghost town in the Mineral Park valley of the Cerbat Mountains in Mohave County, Arizona. [6] Its ruins and cemetery are now located within the property of the mine. [7] Mining in the area began in 1871 and a camp was established soon after. The mines produced primarily silver, gold, copper, lead and zinc.
