Copper Mining In The United States
In the United States, copper mining has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017, the US produced 1.27 million metric tonnes of copper, worth $8 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru. Copper was produced from 23 mines in the US. Top copper producing states in 2014 were (in descending order) Arizona, Utah, New Mexico, Nevada, and Montana. Minor production also came from Idaho and Missouri. As of 2014, the US had 45 million tonnes of known remaining reserves of copper, the fifth largest known copper reserves in the world, after Chile, Australia, Peru, and Mexico.''Mineral Commodity Summary'' - U.S. Geological Survey - January 2018 Copper in the US is ...

Schist
Schist ( ) is a medium-grained metamorphic rock generally derived from fine-grained sedimentary rock, like shale. It shows pronounced ''schistosity'' (named for the rock). This means that the rock is composed of mineral grains easily seen with a low-power hand lens, oriented in such a way that the rock is easily split into thin flakes or plates. This texture (geology), texture reflects a high content of platy minerals, such as mica, talc, chlorite group, chlorite, or graphite. These are often interleaved with more granular minerals, such as feldspar or quartz. Schist typically forms during regional metamorphism accompanying the process of mountain building (orogeny) and usually reflects a medium Metamorphism#Metamorphic grades, grade of metamorphism. Schist can form from many different kinds of rocks, including sedimentary rocks such as mudstones and igneous rocks such as tuffs. Schist metamorphosed from mudstone is particularly common and is often very rich in mica (a ''mica schis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hornblende
Hornblende is a complex silicate minerals#Inosilicates, inosilicate series of minerals. It is not a recognized mineral in its own right, but the name is used as a general or field term, to refer to a dark amphibole. Hornblende minerals are common in Igneous rock, igneous and metamorphic rocks. The general formula is . Physical properties Hornblende has a Mohs scale of mineral hardness, hardness of 5–6, a specific gravity of 3.0 to 3.6, and is typically an opaque green, dark green, brown, or black color. It tends to form slender prismatic to bladed crystals, diamond-shaped in cross section, or is present as irregular grains or fibrous masses. Its planes of cleavage (crystal), cleavage intersect at 56° and 124° angles. Hornblende is most often confused with the pyroxene series and biotite, biotite mica, which are also dark minerals found in granite and charnockite. Pyroxenes differ in their cleavage planes, which intersect at 87° and 93°. Hornblende is an inosilicate (cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hayden, Arizona
Hayden is a town in Gila and Pinal counties in Arizona, United States. According to the 2010 census, the population of the town was 662. History Hayden was founded in 1909 and owned by the Kennecott Copper Corp. In 1912, the company built a smelter named the "Hayden Smelter". It was the tallest smelter chimney in Arizona. The mine is now owned by the American Smelting and Refining Company. The town is now in the process of becoming a ghost town. One of the main reasons the people are abandoning the town is that the crime rate is much higher in Hayden than the Arizona average crime rate. It is also much higher than the national average crime rate in the rest of the United States. Pollution is another factor which has contributed to the abandonment of the town by its residents. The illegal amounts of lead, arsenic and eight other dangerous compounds released by the smelter were so huge that in 2011, the U.S. Environmental Protection Agency (EPA) took action against the smelt ...
