The Escondia concentrator, which has been expanded to handle 127,000td of ore.
The Escondida copper-gold-silver mine is located in the arid, northern Atacama Desert of Chile about 160km southeast the port of Antofagasta, at an elevation of 3,050m above sea level. The mine is a joint venture between BHP-Billiton 57.5, Rio Tinto 30, a Japanese consortium 10 and the International Finance Corporation 2.5. It came on-stream in late 1990 and its capacity has since been increased by phased expansions to the current level of 230,000td ore throughput. The mine employs around 2,200 people.
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 lower-grade ores while maintaining the concentrator throughput, thus reducing the impact on per-ton-treated costs. Output was subsequently ramped up again, and during 2004 the mine handled 377Mt of ore and waste and processed 82.4Mt of sulphide ore grading 1.51 copper up from 70.3Mt at 1.43 copper in 2003.
During the year ending June 2006, the mine handled 368.3Mt of ore and waste and processed 87.7Mt of sulphide ore grading 1.61 copper. Total mill output was 1,207,100 tons. Payable copper production was 1.17Mt of copper, electrowon copper cathode output was 116,300 tons, payable gold in concentrate was 139,000oz and payable silver in concentrate was 5.9Moz.
In 2007, the copper mine boosted output by 18.2 after producing 1.245 million tons of copper contained in concrete and 238,357 tons in cathodes. However, during the first nine months of 2008, Escondida experienced a 10.4 production rate compared to the same period a year ago. Escondida8217s production is recovering however with new resources discovered at Chimborazo and through further brownfield exploration. Copper production is expected to be over 1.3 million tons by 2015.
Escondida is related geologically to three porphyry bodies intruded along the major Chilean west fissure fault system. Primary hydrothermal sulphide ore grades at between 0.2 and 1 copper. Subsequent weathering and uplifting created a barren, leached cap, up to 180m thick, over a high-grade supergene enriched ore, both overlying the primary sulphides. Primary sulphide mineralisation includes pyrite, chalcopyrite and bornite, with covellite and chalcocite in the enriched zone.
The combined proven and probable ore reserves of Escondida and Escondida Norte as at mid-2004 were 2,018Mt of copper sulphide ore at 1.24 total copper 1,701Mt of low-grade copper sulphide ore at 0.55 total copper and 290Mt of copper oxide ore at 0.73 acid-soluble copper.
Hand-crafted Copper Moonshine Stills. Copper is the preferred material in the construction on any moonshine still. A copper moonshine still removes all the sulfides that are produced during the distilling process. The most demanding distillers demand copper for their moonshine stills. Just rinse with water when youre finished and youre done.
1993 and 1994 expansions increased capacity from the initial level of 320,000ty of copper-in-concentrates to 480,000ty. Further expansion in 1996 took output capacity to 800,000ty. In November 1998, concentrator expansion was completed, increasing capacity to 127,000td of ore. A new oxide ore processing plant then began operation, reaching its design rate of 125,000ty of electrolytic copper metal in mid-1999. The 1.044bn 110,000td Phase 4 concentrator was completed in September 2002 using retained earnings.
The project partners invested 400m in opening the Escondida Norte pit, 5km north of the existing mine. By the end of 2004, 126Mt of material had been moved during pre-stripping operations, and the first production started in 2005. Ore is moved by conveyor to the existing treatment facilities.
1. Overview of Mining and its Impacts1 Proposed mining projects vary according to the type of metals or materials to be extracted from the earth. The majority of proposed mining projects involve the extraction of ore deposits such as copper, nickel, cobalt, gold, silver, lead,.
In the United States, the first copper mine was opened in Branby, Connecticut, in 1705, followed by one in Lancaster, Pennsylvania, in 1732. Despite this early production, most copper used in the United States was imported from Chile until 1844, when mining of large deposits of high-grade copper ore around Lake Superior began.

Minera Panama S.A. has revised the original 2008 purchase of Metso grinding mills for the Cobre Panama project and has confirmed the resizing of the mills. The original grinding mill supply has now been revised to be two SAG mills Fig. of 40ft 12.2m in diameter and four ball mills of 26ft 7.9m in diameter. This change is the consequence of a more detailed throughput modeling conducted as part of the Basic Engineering phase and will provide a reasonable design margin over the nominal throughput of 150000dmtpd. Delivery will be completed by the end of 2013.
The Cobre Panama project is located approximately 100kilometers west of the Panama Canal. It is estimated that start-up will commence by the end of 2015. Once the new Cobre Panama mine is in full operation, the concentrator will be capable of processing ore at a rate of 150000 dmtpd over the first 10-years of operation. According to figures included in the FEED Report March 2010 the average annual metal production rate over the first 16-years has been estimated at 289000 tons of copper, 108000 ounces of gold, 1.544million ounces of silver and 3600tons of molybdenum.
The original order was included in Metsos order backlog in Q22008 and the upgraded value of 54million is now included in order backlog in Q22011.
