Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.

Chuquicamata (/ tʃ uː k iː k ə ˈ m ɑː t ə / chookeekəMAHtə), or "Chuqui" as it is more familiarly known, is by excavated volume the largest open pit copper mine in the world, 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.
May 13, 2019· The Chilean Collahuasi Mine in the Pica district of the Tarapacá region produces more than 5,000 tons of fine copper per year, making it one of the largest copper mines in the world. Two opencast mines, Rosario and Ujina, provide the necessary copper ores, which are smelted on site into copper concentrate and cathodes.
The Cerro Colorado porphyry copper deposit is the northernmost currently active copper mine in Chile. It belongs to one of the Paleocene to early Eocene porphyry copper deposits that are distributed along the western slope of the main Andean Cordillera in Northern Chile. The geological evolution of Cerro Colorado area can be generalized as follows.
Zaldivar is located in the Andean Precordillera in Region II of northern Chile, approximately 1,400 kilometers north of Santiago and 175 kilometers southeast of the port city of Antofagasta. The mine lies at an average elevation of 3,000 meters. Zaldivar is an openpit, heapleach copper mine.
Jun 25, 2019· The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40 percent of the world's total copper mine capacity.

Fluor provided engineering, procurement, construction management, and startup services to Compañía Minera El Indio for gold, silver, and copper processing facilities at a site 14,000 feet up in the Chilean Andes. Fluor implemented innovative techniques to complete this project in the remote mountains of Chile.
Escondida copper, gold and silver production. Production at the mine was cut back during the period 2003 on account of the weak world market conditions for copper. The partners in the project decided to mine lowergrade ores while maintaining the concentrator throughput, thus reducing the impact on pertontreated costs.
The mining sector in Chile is one of the pillars of Chilean economy and copper exports alone stands for more than one third of government income. Most mining in Chile is concentrated to the Norte Grande region spanning most of the Atacama Desert. Mining products of Chile includes copper, gold, silver, molybdenum, iron and coal
some of the country’s major copper mines and companies. Chile’s copper reserves exceed 190 million of metallic copper, 28% of the world’s total (6). Codelco Chile is the largest copper mining company, producing 11% of world’s copper and controlling approximately 15% of the world’s proven and inferred copper reserves.
Quebrada Blanca is an open pit operation, which leaches the ore to produce copper cathodes via processing in an SXEW plant. Copper cathode is trucked to Iquique for shipment to purchasers. Mine personnel live in a camp facility, and the majority commute from large population centres, including Iquique, Arica and Santiago.
Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (% by mass). Ideally, the figure should be closer to 2%. The world’s largest copper ore deposits are found in Chile on the west coast of South America. This is due to the volcanic activity that is part of the process that created the Andes mountain chain.
