United States of America v. Reserve Mining Company, 408 F. Supp. 1212 (D. Minn. 1976), was a United States District Court for the District of Minnesota case that determined the Reserve Mining Company was responsible for amphibole asbestos fibers found in the public drinking water of Duluth, Minnesota and other North Shore (Minnesota) communities.
After the discovery of taconite in the late nineteenth century, scientists struggled to find ways to extract iron ore from this sedimentary rock, which contains 25 to 30 percent iron. The process that was eventually developed involves crushing the hard rock into a powder-like consistency. The iron ore is then removed with magnets and turned into pellets.
By 1955, the Reserve Mining Company complex was built to extract iron from taconite. A new town, Silver Bay, was constructed to support it. For every ton of iron ore produced, however, two tons of waste material was leftover. The Reserve Mining Company dumped the waste material, called tailings, into Lake Superior. Permits to do this were approved by the state.
The waste material was initially considered no more harmful than sand. But by the late 1960s, local environmental groups, commercial fishermen, and sport-fishing groups began to complain about the taconite sediment. They argued that the tailings were killing fish, permanently clouding the pristine waters, and spoiling Lake Superior as a freshwater source for Duluth and the surrounding communities.
Environmental organizations, scientists, and lawyers made the case that the tailings not only polluted Lake Superior but that they contained cummingtonite-grunerite. This substance is found in asbestos, a known carcinogen.
On February 17, 1972, on behalf of the Environmental Protection Agency (EPA), the Department of Justice filed a lawsuit against the Reserve Mining Company in U. S. District Court in Minneapolis. This led to a trial that would last over a year. Appeals dragged the case on until 1980. Judge Miles Lord presided over the court.
Pretrial arguments took a turn in June 1973. The federal government called a specialist in asbestos exposure, Dr. Irving Selikoff, from the Mount Sinai School of Medicine in New York. Dr. Selikoff argued that the lake contained asbestos-like fibers. He also said he thought a thorough study should be done on the effects of the lake water on the human body. Judge Lord put Dr. Selikoff's testimony under an order of secrecy, but the information wasn't contained. Eventually, Lord allowed the EPA to issue an asbestos warning to the public.
The asbestos issue defined the trial when it officially began in August 1973. The public, already alarmed by reports of asbestos deaths around the country, was fixated on the trial. It was also covered in the national press.
The Reserve Mining Company claimed that it was impossible to dump the tailings on land. During the trial, however, subpoenaed documents showed that Reserve had already examined dumping the sediment on land as an alternative method of disposal.
Both the federal government and Reserve relied on a prestigious lineup of scientists to buttress their case. After months of testimony, Judge Lord decided that dumping the tailings into Lake Superior posed serious health and environmental threats. In April 1974 he ordered the plant shut down.
The plant was closed temporarily. But a federal appeals court allowed Reserve to reopen the mine and to continue dumping in the lake until the company could find a new disposal method. In 1980, Reserve began to deposit waste in an inland pond. This practice continues with the companies that mine taconite today.
The ruling in United States of America v. Reserve Mining Company was considered a landmark decision. It gave the EPA broader powers to regulate corporate pollution, a practice was unheard of before the lawsuit.

The Mesabi Iron Range is a mining district and mountain range in northeastern Minnesota following an elongate trend containing large deposits of iron ore. It is the largest of four major iron ranges in the region collectively known as the Iron Range of Minnesota. First described in 1866, it is the chief iron ore mining district in the United States. The district is located largely in Itasca and Saint Louis counties. It has been extensively worked since 1892, and has seen a transition from high-grade direct shipping ores through gravity concentrates to the current industry exclusively producing iron ore (taconite) pellets. Production has been dominantly controlled by vertically integrated steelmakers since 1901, and therefore is dictated largely by US ironmaking capacity and demand.
Taconite is a variety of banded iron formation, an iron-bearing sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate. The name "taconyte" was coined by Horace Vaughn Winchell (1865–1923) – son of Newton Horace Winchell, the Minnesota State Geologist – during their pioneering investigations of the Precambrian Biwabik Iron Formation of northeastern Minnesota. He believed the sedimentary rock sequence hosting the iron-formation was correlative with the Taconic orogeny of New England, and referred to the unfamiliar and as-yet-unnamed iron-bearing rock as the 'taconic rock' or taconyte.
The Iron Range is collectively or individually a number of elongated iron-ore mining districts around Lake Superior in the United States and Canada. Much of the ore-bearing region lies alongside the range of granite hills formed by the Giants Range batholith. These cherty iron ore deposits are Precambrian in the Vermilion Range and middle Precambrian in the Mesabi and Cuyuna ranges, all in Minnesota. The Gogebic Range in Wisconsin and the Marquette Iron Range and Menominee Range in Michigan have similar characteristics and are of similar age. Natural ores and concentrates were produced from 1848 until the mid-1950s, when taconites and jaspers were concentrated and pelletized, and started to become the major source of iron production.
The Duluth, Missabe and Iron Range Railway (DM&IR), informally known as the Missabe Road, was a railroad operating in northern Minnesota and Wisconsin that used to haul iron ore and later taconite to the Great Lakes ports of Duluth and Two Harbors, Minnesota. Control of the railway was acquired on May 10, 2004, by the Canadian National Railway (CN) when it purchased the assets of Great Lakes Transportation.
The Arrowhead Region is located in the northeastern part of the U.S. state of Minnesota, so called because of its pointed shape. The predominantly rural region encompasses 10,635.26 square miles (27,545.2 km2) of land area and includes Carlton, Cook, Lake and Saint Louis counties. Its population at the 2000 census was 248,425 residents. The region is loosely defined, and Aitkin, Itasca, and Koochiching counties are sometimes considered as part of the region, increasing the land area to 18,221.97 square miles (47,194.7 km2) and the population to 322,073 residents. Primary industries in the region include tourism and iron mining.

Elcor is a ghost town, or more properly, an extinct town, in the U.S. state of Minnesota that was inhabited between 1897 and 1956. It was built on the Mesabi Iron Range near the city of Gilbert in St. Louis County. Elcor was its own unincorporated community before it was abandoned and was never a neighborhood proper of the city of Gilbert. Not rating a figure in the national census, the people of Elcor were only generally considered to be citizens of Gilbert. The area where Elcor was located was annexed by Gilbert when its existing city boundaries were expanded after 1969.

Twin Metals LLC is seeking approval to create and operate a copper sulfide mine near Ely, Minnesota, on Superior National Forest land. There has been significant opposition to the proposed mine, most notably because of its proximity to the Boundary Waters Canoe Area Wilderness, location within a watershed that drains into the BWCA, and the air, water, light and noise pollution and traffic effects of converting a forested area bordering the BWCA into a substantial industrial mining facility. Twin Metals is a subsidiary of the Chilean conglomerate Antofagasta, which is controlled by billionaire Andrónico Luksic. The original lease is a 1966 lease to the International Nickel Corporation.
