Copper - Essential Chemical Industry

Copper is obtained from its ore by treating the ore with a solution of copper(ll) chloride and iron(lll) chloride: To keep the compound in solution, sodium chloride is added. In the presence of excess chloride ion, the complex ion [CuCl 2 ] - is formed, which is soluble in water:Innovations in Copper: Mining & Extraction: Producing .Capital costs at this level of operation were to be US$0.08/lb of copper and operating costs, as shown in Table 2, were estimated at US$0.34/lb of copper. 28 The average ore grade is 0.59% copper and the estimated recovery is 78.2%.Chapter 6 Copper Production Technology107 Figure 6-2.—Early Smelting Technology Charcoal ore flux m The Egyptian copper smelting furnace was filled with a mixture of copper ore, charcoal and iron ore to act as a flux.
