Since 1960 the number of deposits developed per 10-year period has greatly increased without a commensurate increase in tonnage of copper. This is in part due to the fact that recent exploration successes have been increasingly repre- sented by smaller and (or) lower grade.how much copper from 14 million tons of ore,With nonferrous-metal demand rising, pressures for production from .Jul 11, 2011 . The PolyMet project calls for surface mining and mineral processing of approximately 228 million tons of copper-nickel-platinum ore over approximately a 20-25 year mine life. PolyMet expects to mine, on average, 91,200 tons per day of material, which would include about 32,000 tons of ore and 3,900 tons.John Frank
The US Geological Survey estimated that, as of 2013, there remained 3.5 billion metric tons of undiscovered copper resources worldwide in porphyry and sediment-hosted type deposits, two types which currently provide 80% of mined copper production. This was in addition to 2.1 billion metric tons of identified resources.

China has consumed refined copper up to 95 million ton (Mt) for economic development from 1949 to 2013, which is mainly concentrated in equipment (36%) and .. Copper lifecycle includes extraction from ores, production of copper containing products, consumption, accumulation in social stock and scrap recycling.
Dec 14, 2017 . Copper tonnage is much smaller than coal, at ~20 million tons versus that 3-4 billion in coal from surface mines, but low and falling ore grades make it more . Copper makes up around 14% of global mining equipment installed base, so the 18% increased copper demand to power 30 million electric vehicle.
Feb 27, 2017 . 6, 2013, mine operators granted access to see the progress that has been made with 14 million tons of material removed so far following the 150 million ton . because the reports tend to overemphasize the releases produced by mining operations — and, in Utah, that means the Kennecott copper mine.
Aug 14, 2011 . Summary. The Kennecott Copper Mine, for a time the largest copper mine in the world, operated from 1911 to 1938 in what is now Wrangell St. Elias National Park. The mine produced a total of around 4.6 million tons of ore, valued at over $200 million (~$3 billion in 2011 dollars). The Alaska Syndicate.

Recycling diverts 150 million tons of material away from landfills. Recycling reduces greenhouse gas emissions by requiring significantly less energy to manufacture products from recyclables than ore and by avoiding landfills. Energy saved using recycled material vs. ore: 95% for aluminum, 85% for copper,.
Recycling one ton of aluminum conserves up to 5 tons of bauxite ore and 14 mega-watt hours of electricity. Energy Saved using aluminum . One metric ton of circuit boards can contain 40 to 800 times the amount of gold and 30 to 40 times the amount of copper mined from one metric ton of ore in the US. For every million.
“We are consuming copper at much higher than our average rate, much higher than our rate will be say one, two, or three years hence,” Church said. Whatever the trend of .. In World War II copper production was maintained at the record level of one million tons a year without substantial price increases. The ceiling was.
Every year the metals sector produces: 14 million tonnes of steel; 1.2 million tonnes of castings; 500,000 tonnes of aluminium. It reclaims and processes 10 million tonnes of used or end-of-life metals. The metals sector is at the forefront of innovation. 70% of steels used in automotive applications did not exist 10 years ago.
