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 the nation's lead.
Feb 11, 2020· The Chippewa and Potawatomi tribes purchased the site in 2003. There is no current mining activity. The ore deposit is 4,900 feet long, 2,200 feet deep and 100 feet wide. It has an estimated 55 million tons of ore containing …
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 without ...
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.
Wisconsin has 1,148 identified mines listed in The Diggings™. 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 ...
Apr 30, 2019· Gold was first discovered in Wisconsin towards the end of the 19th century. Numerous discoveries were made but they were never sizeable enough to warrant commercial mining. Today, prospecting in Wisconsin is strictly recreational. On occasion it can be fun and rewarding to prospect here in The Badger State.
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."
May 13, 2019· Wisconsin's Frac Sand Boom. Frac sand mining boomed in Wisconsin between 2010 and 2015 with companies from around the United States building mines, processing plants and rail loading facilities in hopes of capitalizing on the state's reserves of silica sand the industry calls "Northern White." It was prized for its strength and roundness, and ...
Those early mining activities concentrated on extracting naturally high-grade hematitic ore until those bodies were largely exhausted by the 1960s. As there is still a large quantity of taconitic-grade iron ore available in the western Gogebic deposit, it is the primary site of contemporary iron mining speculation in Wisconsin.
Dec 18, 2019· Unlike iron ore mining, copper-nickel mining has the potential to create an acidic runoff that can leach heavy metals into water. The phenomenon, known as "acid mine drainage," happens when ...
Mining Regulations Recreational gold panning is not directly addressed in the existing mining laws or regulations. The statute and administrative codes regulating metallic mining activity in Wisconsin (ch. 293, Stats., and chs. NR 130, NR 131, NR 132 Wis. Adm. Code), mostly focus on commercial operations. Therefore, the Department of Natural
Wisconsin has some interesting varieties of rocks and minerals that you can collect. The beautiful Lake Superior Agates are very popular to find along the shoreline. Huge copper nuggets have also been found with metal detectors in Wisconsin. Malachite is also associated with some copper deposits.
A total of 1,084 mines and prospects in 85 metallic min eral districts are located on the accompanying maps of the Black Hills. Except for a few placer districts, all metallic mineral districts contain mines that produced, or are inferred to have produced, ore. Individual districts may overlap one
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.

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
dominated the metallic mining industry in the state through the 1980s. Until the early 1960s, the Precambrian rocks of northern Wisconsin were viewed as being favorable only for the occurrence of iron deposits and possibly copper deposits similar to those found in the upper peninsula of Michigan. That view changed after the discovery of several ...
Mar 24, 2014· The deposit contains 20-30% iron in the form of magnetite. Because the iron ore is of lower grade than the natural hematitic ores mined previously in northern Wisconsin, the ore must be concentrated and processed into taconite pellets prior to shipping to a steel mill. Gogebic Taconite, LLC, withdrawal
