The Michigan Copper Mining Co. holdings consisted of 4,870 acres of mineral land, 1,466 acres of timber land and a 150 acre mill site. This included the sites and of the old Minesota, Superior and Rockland mines. The new workings eventually included A, B, C and E shafts.
The open pit mine operation uses primary crushing, SAG milling, AG milling, pebble crushing, ball milling, bulk sulfide flotation and molybdenum separation to produce copper and molybdenum concentrates. Teck expected the optimization project to increase copper recovery by 2 percent and increase mill output by 10 percent.
Mar 19, 2017 Porphyry copper ores, usually medium to medium hard, require grinding to about 65 mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65 mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary.
Nov 30, 2020 Copper Mountain Mining has announced an updated life of mine plan, completed at a pre feasibility study level, for its 75 owned Copper Mountain mine in southern B.C.

Copper. Copper is a reddish, relatively abundant, easily worked metal with a bright metallic luster. Its chemical symbol is Cu. Copper occurs as a native metal and as compounds (frequently of sulfur) that are easily smelted. It is a good conductor of heat and electricity, and its main uses are in electrical wire, plumbing, roofing, coins, and.
Most widespread minerals containing Copper This list of minerals containing Copper is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock forming minerals so it does not give an undistorted distribution of Copper mineral species.
Feb 20, 2021 Hudbay Minerals produced 60.1 million lb copper, 32,376 toz gold, 57 million lb zinc, 731,000 toz silver, and 734,000 lb molybdenum in Q4. The AISC declined to $2.16 lb copper.

Photo of the Knob Hill Mill, circa 1949, which was part of the Republic Mining District, one of the largest producing area of gold and silver in Washington.
The mine, mill, and most of the smelter closed in 1982. However, the company continued smelter operations to produce copper from scrap material until 1984, when the facility completely shut down (Copper Range Co.
The Minto mine commenced Yukon mining operations in 2007 as an open pit mine. In 2012 the company began underground development on the Minto South Deposits while continuing to mine additional open pits as the primary mining method. Today, the mining is entirely underground and we are currently producing in the Copper Keel ore body.
Copper Mountain Mining has released a new technical report for its open pit Copper Mountain mine in southern British Columbia. The report includes a new life of mine plan and a proposed mill expansion to 65,000 tonnes of ore per day, which would boost the mine’s estimated net present value to.
The Kennecott Mines and mill town are an abandoned copper mine operation and ghost town in Alaska that together, form a National Historic Landmark District. Located within the Wrangell St. Elias National Park Preserve, this historic site tells a story of discovery, perseverance, and ingenuity at a time when America was hungry for copper to build railroads, electrify cities and supply.
Copper City is located 70 miles north of Yakima WA along Deep Creek in the Bumping Mining District of Yakima County. The minerals at Copper City were first discovered in the 1890's. The claims were sold to the Copper City Mining Company in 1905. In 1906 a sawmill was constructed at the Copper City site for further development work of the mining.

The nci mine is a porphyry copper deposit that has oxide, secondary sulfide and primary sulfide mineralization. The predominant oxide copper mineral is chrysocolla. Chalcocite is the most important secondary copper sulfide mineral, with chalcopyrite as the dominant primary copper sulfide.
The Enterprise mine is a major copper ore source at Mount Isa and is Australia’s deepest mine, with an internal shaft, which reaches a depth of 1,900m. Copper production at Mt Isa, Queensland, is derived from separate orebodies from those that form the basis for lead and zinc mining, with the copper operations being regarded as standalone.
Collahuasi copper mine 180km south east of the port of Iquique in northern Chile ranks as the third largest copper mine in the world. Proven and probable copper reserves of the open pit mine as of December 2012 stood at 25.895Mt. The mine produced 282,096t of copper in 2012, accounting for 5.1 of Chile’s total copper output.
The 4.0 Mt y Minerals Processing Plant (MPP) is designed to produce copper concentrate, processing ore delivered from the underground mine. At a high level, the plant consists of the following major design sections Coarse Ore Stockpile and Reclaim. Coarse ore stockpile with a live capacity of 12,000t, allowing for 24 hours of mill feed.
