Dec 02, 2011· 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.
Most of the gold found prospecting in Wisconsin is very fine textured flour gold, brought down from Canada and deposited by glaciers. This glacial gold does not accumulate in large enough quantities to interest large mining companies, but recreational prospectors can find placer gold throughout the streams and rivers of Wisconsin.
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.
Metallic minerals are further divided into ferrous minerals, which contain mainly iron, and nonferrous minerals, which do not contain iron but have other metals such as copper.

— Copper at the Wisconsin Mine (Edwards Mine) NE SE Sec. 2 T.47N R.13W occurred as "shot and nugget" ore with copper masses weighing 1-15 lbs. Associated minerals are prehnite, calcite, quartz and epidote (Sweet, 1880).
Over the past twenty-five years of metallic mineral exploration in northern Wisconsin, four orebodies (areas of mineralization that may be economically feasible to mine) have been located and defined. One, the Flambeau Mine near Ladysmith has been successfully reclaimed. Reclamation of the pit began in early 1997 and was completed in late 1998.
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
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 ...
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.
With the potential for such impacts, effective mining laws and regulations must be enforced and strengthened. Metallic mining – including iron ore. The extraction of metallic minerals such as iron, zinc or copper has a long history in Wisconsin, but legal regulation of their environmental impact and safety are a relatively recent development.

The most commonly listed primary commodities in Wisconsin mines are Lead, Zinc, and Copper .At the time these mines were surveyed, 127 mines in Wisconsin were observed to have ore mineralization in an outcrop, shallow pit, or isolated drill hole—known as an occurance mine. 1 Wisconsin has 40 prospect mines. 2 974 mines were in ...
Mining in Northern Wisconsin. However, northern Wisconsin remained largely untouched by white settlement for several more decades. There were o nly a few fur trading posts, lumber camps and small ports throughout the region. But in the 1840s three forces drew settlers into Northern Wisconsin. First, lead mining in the south decreased.

Wisconsin serves as home to a variety of semi-precious gemstones, which can be cut and polished for jewelry, but a few Madison diamonds from the Wisconsin area have a bit of history associated with them. The Eagle Diamond, weighing 16.25 carats, was stolen from a NY museum in the 1960s.
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.
Aug 16, 2011· With metal prices soaring and mining companies feeling more welcome under Gov. Scott Walker's "open for business" philosophy, mineral exploration is going on at a level not seen in nearly 30 years in northern Wisconsin.
