Nickel Mining
A nickel mine is a mine that produces nickel. Some mines produce nickel primarily, while some mines produce nickel as a side-product of some other metal that has a higher concentration in the ore. Geology Nickel occurs in two general types of ores, sulfides and oxides. The most important sulfide ore is pentlandite (Ni9S8) although many other nickel sulfides are known. Furthermore, nickel is often a constituent of iron sulfides such as pyrrhotite. The principal (i.e. economically most important) nickel oxides are nickeliferous limonite ((Fe1−xNix)O(OH)·nH2O). Pentlandite supplies an estimated 65% of the world's nickel but nickel laterites constitute the largest reserves. Extraction Nickel content of its ores is often only a few percent by weight. Sulfide ores are subjected to commutation followed by froth flotation. Pentlandite and related minerals separate with sulfides of copper, cobalt, and iron. Two hydrometallurgical methods have been developed to extract nickel and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nickel Mine At Hamn, Senja, Troms, Norway, 2014 August
Nickel is a chemical element with Chemical symbol, symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and Ductility, ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under Standard conditions for temperature and pressure, standard conditions because a Passivation (chemistry), passivation layer of Nickel(II) oxide, nickel oxide forms on the surface that prevents further corrosion. Even so, pure native metal, native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger iron meteorite, nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric iron, Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer core, Eart ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thompson, Manitoba
Thompson (population 13,678) is the largest city in the Northern Region of Manitoba and is situated along the Burntwood River, north of Winnipeg. Originally founded in 1956 as a mining town, it now primarily serves as the "Hub of the North", providing goods and services such as healthcare and retail trade to the surrounding communities. Thompson's trade area is larger than New Mexico, yet it has fewer than 15,000 residents, with many of the smaller communities accessible only by air or winter road. Despite its isolated location in the heart of Canada's boreal forest, it is connected to Winnipeg via paved highway, railway (Via Rail), and Thompson Airport. It also has modern amenities, such as fibre optic internet and a large retail scene, including half a dozen shopping malls and several large chain stores (e.g., Walmart, Giant Tiger, Safeway, Shoppers Drug Mart and Canadian Tire). Thompson's natural and undisturbed surroundings make it popular with outdoor enthusiasts. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ravensthorpe, Western Australia
Ravensthorpe is a town 541 km south-east of Perth and 40 km inland from the south coast of Western Australia. It is the seat of government of the Shire of Ravensthorpe. At the , Ravensthorpe had a population of 438. In 1848, the area was surveyed by Surveyor General John Septimus Roe who named many of the geographical features nearby, including the nearby Ravensthorpe Range that the later town was named after.

Ravensthorpe Nickel Mine
The Ravensthorpe Nickel Mine is a nickel mine and hydrometallurgical processing plant located at Bandalup Hill, east of Ravensthorpe, Western Australia. Built by BHP Billiton, it was closed in January 2009, after less than a year of operation due to a collapse in the price of nickel. It was sold in December 2009 to First Quantum Minerals who reopened the mine in December 2011, after 18 months of modifications and re-commissioning. Following a period of low nickel prices, the operation was placed on care and maintenance in October 2017. Production recommenced in January 2020 with POSCO purchasing a 30% shareholding in May 2021. History Mining in Ravensthorpe considerably predates the current nickel mine, with gold discoveries dating back to 1898. The town experienced a down turn after World War I but mining for copper continued up until the 1970s. A railway line connected Ravensthorpe with the port of Hopetoun from 1901 to 1925, when the line was closed. BHP Billiton commence ...

Nickel Mining In Western Australia
Nickel mining in Western Australia has been an industry that has had many fluctuations of fortune in its history. Large fluctuations in the world nickel price have seen mines close and reopen on several occasions. In 2004/05, the value of nickel production ($2.7 billion) exceeded that of gold ($2.2 billion). In the 2011 calendar year, nickel contributed $3.9 billion or four per cent to the value of the State's resources. Nickel production in the same year was 188,000 tonnes. Australia (predominantly Western Australia) holds one-third of the world's known reserves of nickel-producing laterites and sulfide deposits. As of 2011, Australia was the world's fifth largest nickel producer. The only other significant Australian nickel production outside Western Australia is a refinery at Yabulu, Queensland which processes ore from New Caledonia, Indonesia, and the Philippines. Early mines Nickel mines were developed in the late 1960s in Kambalda, Laverton and the Kimberley region o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
