Comment (Development): From: http://www.ritchiewiki.com/wiki/index.php/Bingham_Canyon_Mine Today, the mining of chalcopyrite, or copper iron sulfide, is done in steps, causing the mine to resemble an inverted pyramid.Explosives are used to loosen the ore contained in the rocks. Holes measuring 55 feet (17 m) deep and 12 inches (30.5 cm) in diameter are made with rotary drills and packed with half-ton loads of explosives. Once detonation has occurred, electric shovels move the huge resulting piles of rubble into 240- to 320-ton rock trucks. Some shovels are capable of lifting almost 100 tons of rock in a single scoop. The rock trucks haul the ore to an on-site crusher and then five-mile (8-km) long conveyor transports the ore to the Copperton concentrator. After arriving at the Copperton concentrator, the ore is ground by steel balls in massive mills and then concentrated using the flotation separation process. The resultant 28 percent copper concentrate is moved in a slurry pipeline to the smelter, which is located 17 miles (27.4 km) away.At the smelter, a large rotating dryer is used to dry the slurry. Next, the slurry is separated into three products in the flash smelting furnace: sulfur-rich gases; a mixture of silica and iron known as slag; and copper matte, which is 70 percent copper. Once cooled, the copper matte is crushed and put in a flash converting furnace. This furnace removes most of the impure particles to produce blister, a molten copper that is approximately 98 percent pure. Anode furnaces are used for further refining. The copper is cast in plates called anodes, which are 99.6 percent copper and weigh about 700 pounds (317.5 kg). An acid solution and an electric current are used to remove remaining impurities and produce 99.99 percent pure copper. The operators of the Bingham Canyon mine thought they would have to use block cave mining to obtain copper from the mine after 2012. This would have required an investment of more than $1 billion in new infrastructure and the mine was slated for closure. Block cave mining entails digging tunnels under the ore body, forcing ore to fall either by the force of gravity or blasting.Instead, in 2005, Rio Tinto committed $170 million to a major mine expansion project known as the East 1 Pushback, which will extend the open-pit mine 600 feet to the east and keep it operational until at least 2013. Before the ore-rich zone is reached, approximately 1,700 vertical feet (518 m) of rock will be excavated.

Comment (Development): From: http://www.ritchiewiki.com/wiki/index.php/Bingham_Canyon_Mine The underground mining boom in Bingham Canyon lasted through the 1870s and 1880s. By the early 1890s, the miners had exhausted the canyon?s supply of rich, oxidized pockets of gold, silver and copper carbonates. These ores could be smelted immediately, with no need for prior concentration. Low grade, unoxidized sulfides were all that remained?but mining those ores was not economical. In 1898, engineers Daniel Jackling and Robert Gemmell invented a new method of mining and milling that would revolutionize metal mining: flotation separation. This technique was based on the theory that oil-covered mineral particles would adhere to oil bubbles. The process of flotation separation involved mixing finely ground ores with an oily substance, then agitating and aerating this slurry in tanks. While mineral particles stuck to the rising bubbles, non-mineralized rock would fall to the bottom and be discarded. In 1903 Jackling established the Utah Copper Co. and erected a mill at Bingham Canyon with a capacity of 300 tons per day. In 1906, he began using steam shovels, making this the first mechanized open-pit mine in the U.S. He built a second mill in which to run a large-scale floatation separation operation; it turned out to be very successful.Due to the low cost flotation separation method, the mill was able to produce a concentrate containing 23 percent copper and byproduct metals (such as gold and silver). Flotation separation caught on across the country, although Bingham Canyon experienced the fastest growth rate. In 1912 an estimated 65 percent of the workers and residents in the canyon were immigrants. Distinct communities based on ethnicity began to form. By the 1920s, an ethnically diverse group of more than 15,000 people populated the canyon. In 1926, a purpose-built mining town called Copperton was built at the mouth of the canyon. In 1930, Kennecott Utah Copper Corp. purchased the mine property and began to expand the operation. The success of this expansion was evidenced in World War II, when the mine supplied more than one-third of the copper used by the Allied Forces.In the 1980s, the huge mine employed nearly 8,000 people. While 2,500 were responsible for drilling and blasting 370,000 tons of rock every day, 5,200 had the task of hauling, concentrating, smelting, and refining the product. The mine produced was 300,000 tons of pure copper annually. At the same time, Bingham Canyon was beginning to experience major competition from foreign copper producers that were able to supply the product for a fraction of the cost. In 1982, when copper prices dropped sharply, Bingham Canyon lost money and operations ceased for the first time since the mine's establishment. Kennecott Utah Copper Corp., recognizing that the mine still yielded a valuable product, invested $1.5 billion over the next decade to upgrade the mine, concentrator, smelter, and refineries in an effort to increase the operation's competitiveness. The mine is now recognized as one of the safest, cleanest, and most efficient in the world.
