Republic Michigan and the Republic Mine in the Upper

This inactive open pit iron mine, owned by Cleveland Cliffs Iron Company, provides a unique opportunity for viewing by the public. From the observation stand near the pit's edge, you gain an appreciation of the enormous magnitude of planning and effort involved in the mining of low grade, surface deposits of iron ore which supply our nation's steel mills.

The Exploration of Benson Mines

Located at the intersection of NY 3 and County Route 60, Benson Mines in Star Lake New York, produced so much iron ore that in 1958, it became the largest open pit iron ore mine in the world. The plant was so productive that it the local railroad built rail lines directly to the plant. Benson mines closed in 1978, costing an estimated 1200 jobs, and has been abandoned ever since.

Introduction to Mining in the Penokees

Between 1886 and 1965, 71 million tons of iron was taken from several shaft mines, the deepest running almost a mile below Earth's surface. The mines were all shut down by 1965, due to the advent of cheaper-to-operate open pits in Minnesota's Mesabi Iron Range, Michigan's Marquette Iron Range, and competition from inexpensive foreign ores.

Hopewell's Iron Ore Mines

2015/2/26There are three mines located near Hopewell Furnace that the furnace depended upon for its supply of iron ore. The mines are located on three different ore veins a few miles from the furnace. In the beginning all of the mines were open pit processes. Get price

Iron Ore Company of Canada

2020/8/28We have a high-quality iron ore reserve and long mine life. In 2018 we opened a new pit, the Moss pit, at our existing mine site in Labrador. This development will extend the life of our IOC operation, reduce operating costs and sustain production of our quality grade iron concentrates and pellets. Get price

South Africa's Biggest Open Pit Mines

Open pit mining - also called open cut mining or open cast mining - is a surface mining technique used to extract rocks and minerals. It requires large-scale equipment, including shovels and drills. Motor graders also play a role, maintaining haulage roads so that both equipment and mined material can be transported to and from the mines. Get price

History of mining: five of the oldest mines still in operation

The open pit itself is just shy of 1km deep and 4km wide. It was designated as a National Historic Landmark in 1966. Bingham Canyon is estimated to be one of the world's most productive mines. Since 2004, the mine excavated more than 15mt of copper, 718t Get price

Open Pit Mining Techniques

Open-pit mines are characteristically engorged until either the mineral resource is exhausted, or a mounting ratio of overburden to ore makes more mining uneconomic. When this occurs, the exhausted mines are at times converted to landfills for disposal of solid wastes. Get price

Environmental Risks of Mining

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

Reduce ore dilution and loss in open pit mines

In open pit mines the required explosive displaces ore boundaries from where the geologists originally defined them. Failure to accurately account for blast movement results in ore loss, dilution, or misclassification (low grade to high grade ore, sulfide to oxide, or other contaminates). Get price

Take A Tour Of This Awesome Michigan Iron Mine

During the mid-to-late 19th century, mines were established throughout the region — including several in Michigan. While iron mining is certainly no longer a major source of employment for workers in the Great Lakes State, Michiganders and tourists can still experience remnants of the mining boom with a visit to the Iron Mountain Iron Mine.
