Sep 18, 2012· Overview of metallic mining in Wisconsin. Metallic mining has occurred in Wisconsin since the time of the Copper Culture about 2,000-5,000 years ago. Mining for metals such as copper, lead, iron and zinc shaped the history of several regions of Wisconsin and played a major role in the development of Wisconsin as a state.
Potential Metallic Mining Development in Northern Wisconsin The Flambeau Mine extracted about 1000 tons per day of copper-rich ore. Reclamation of the pit began in early 1997 and was completed in late 1998. The Crandon deposit is presently being evaluated for the required environmental impact analyses and the mining permit and other related

Mining has always been an important part of the Wisconsin way of life. From the native peoples of the Lake Superior copper culture to the recent successful reclamation of the Flambeau copper and gold mine, extraction of marketable minerals has always been a valued industry.

Evans; Mineral and water resources of Wisconsin, 1976, prepared by the US Geological Survey in collaboration with the Wisconsin Geological and Natural History Survey; Iron mining in Wisconsin, 2011, Wisconsin Geological and Natural History Survey Factsheet 3.
Welcome to the Wisconsin Mining Association. Wisconsin's citizens, most of their jobs, the state's economic wellbeing and its as iron ore, copper, zinc, phosphate, molybdenum as well as gold and silver in iron mining existed in western and northern Wisconsin
Writing in 1855, James Gregory declared, "Iron ore of unlimited extent and of great purity may be found at Lake Superior, in the Baraboo district, and at the Iron Ridge in Dodge and Washington counties." Mining in northern Wisconsin served a different purpose than the agricultural development in the southern part of the state.
In recent years there has been much interest in gold discoveries associated with iron ore deposits throughout the state, but the economic viability of mining these resources lies heavily on the value of producing other minerals including lead, zinc, copper, and silver, with gold as a by-product.

Oct 09, 2011· For many in this small city, the $1.5-billion iron ore mine proposed in Ashland and Iron counties by Gogebic Taconite offer a tantalizing way out of a long economic decline in Wisconsin's northern counties that has seen incomes shrink and once
Even the Wisconsin state seal is proudly emblazoned with a rendering of a lead miner as well as a pick and shovel, and lead ore is Wisconsin’s official state mineral. Later, mining companies transitioned to extracting zinc, as well as copper and iron in the northern region of the state.
Lead ore was the first metal ore mined in Wisconsin, followed by zinc and iron. Although southwestern Wisconsin is best known today for its rich farmlands, place names such as Mineral Point, Hardscrabble, New Diggings, Black Jack and Lead Mine evoke an earlier time when local mines produced much of
Iron mining refers to the excavation of iron ore, most of which is used as a key component in the production of steel. Most of the iron ore in Wisconsin can either be classified as taconite (25-35% iron) or high-grade ore (50-70% iron). While Wisconsin is known as an agricultural state, it started as a mining state in the mid-19th century.
A significant resource of high-grade iron ore remains in the western and eastern parts of the range. Mining of the Gogebic Range in Wisconsin began in 1885, and within six months of the development of the mining industry, the city of Hurley went from a population of 80 to more than 2,500 people.
Mining in Northern Wisconsin. Native Americans mined copper on the shores of Lake Superior in prehistoric times. Between 4,000 and 1,200 B.C., copper jewelry and implements from Wisconsin and Upper Michigan were part of a trade network that stretched from the Rocky Mountains to the Gulf Coast, giving rise to the name "Old Copper Culture."
Iron mining in the United States produced 42.5 million metric tons of iron ore in 2015, worth US$3.8 billion. Iron ore was the third-highest-value metal mined in the United States, after gold and copper. Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and Utah.Most of the iron ore was mined in northern Minnesota's Mesabi Range.
Nestled among the trees, streams and undeveloped land in Northern Wisconsin rests an environmental, societal and political challenge. The pristine area, with its proximity to Lake Superior, the largest fresh-water lake in the world, is why its residents choose to live there, but the area is also home to 25 percent of the country’s iron ore reserves, a commercial value of $200 billion.
Apr 01, 2020· In China’s Heilongjiang province on Saturday, water containing waste molybdenum ore mined for the metal used in stainless steel and tools flowed out of a tailings pond belonging to Yichun Luming Mining Co Ltd and into a river system. There were no casualties reported.
Jan 10, 2017· One northern Wisconsin lawmaker would like to repeal the state’s mining moratorium law. Sen. Tom Tiffany, R-Hazelhurst, said he expects to introduce a bill this session.. The mining moratorium law was passed with bipartisan support and signed into law by Gov. Tommy Thompson in 1998. It requires companies to prove a sulfide mine can run for 10 years and be closed for 10 years
Aug 13, 2015· Wisconsin is a state that will yield small amounts of gold for a persistent prospector. It is an interesting state as far as gold is concerned because of its known potential to produce the yellow metal is limited. All gold recovery is done on a small-scale. No significant gold mining
Feb 28, 2015· The company that promised a huge mine in northern Wisconsin announced Friday that it was dropping the controversial project because it is not feasible. Mining of metals runs the risk of exposing waste rock that can create rivers of acidic material that destroys wildlife.
Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water
The Gogebic Range is an elongated area of iron ore deposits located within a range of hills in northern Michigan and Wisconsin just south of Lake Superior.It extends from Lake Namakagon in Wisconsin eastward to Lake Gogebic in Michigan, or almost 80 miles. Though long, it is only about a half mile wide and forms a crescent concave to the southeast. The Gogebic Range includes the communities of
Formula: Ag Isometric Description: Native silver is found in hydrothermal veins or, more rarely, as a supergene mineral. It is associated with gold, and a variety of sulfides such as galena, pyrite and acanthite. Major silver mineralization is found with native copper in nearby Michigan at the White Pine Mine and further north in the Keweenaw Peninsula.
