Chuquicamata (/ tʃ uː k iː k ə ˈ m ɑː t ə / choo-kee-kə-MAH-tə referred to as Chuqui for short) is the largest open pit copper mine by excavated volume in the world  It is located in the north of Chile just outside Calama at 2 850 m (9 350 ft) above sea level 215 km (134 mi) northeast of Antofagasta and 1 240 km (770 mi) north of the capital Santiago
2 Leaching The ore is treated with dilute sulphuric acid This trickles slowly through the ore dissolving copper to form copper sulphate The copper is recovered by electrolytic refining Advantages of this process are much less energy is use than in traditional miningMined from open pits copper ore must be crushed as part of the process that occurs between extraction and production Using today's compact mining equipment copper ore is extracted from the mine After the ore is crushed it's roasted which helps to convert sulfides to oxidesGet price

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99 99% pure copper called cathodes which will ultimately be made into products for everyday use The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different The copper ore reserves at the Chuquicamata mine were re-estimated during March to June 1994 as part of a comprehensive audit of the mine's overall short- and long-term planning The basic principles essential to all ore reserve estimates were implemented viz 1Get price
