Murrin Murrin Joint Venture
The Murrin Murrin Mine is a major nickel-cobalt mining operation being conducted in the North Eastern Goldfields, approximately 45 km east of Leonora, Western Australia. The project was initiated as a joint venture between Murrin Murrin Holdings Pty Ltd, a wholly owned subsidiary of Anaconda Nickel Limited (whose share was 60%) and Glenmurrin Pty Ltd, a wholly owned subsidiary of Glencore International AG, which had a 40% share. In 2003 Anaconda changed its name to Minara Resources Limited. In November 2011, Minara Resources was fully acquired and is now wholly owned by Glencore International.

Leonora, Western Australia
Leonora is a town in the Goldfields-Esperance region of Western Australia, located northeast of the state capital, Perth, and north of the city of Kalgoorlie. History The first European explorer to visit the area was John Forrest in 1869. On 21 June 1869 Forrest's party made camp near a conspicuous hill, which Forrest named Mount Leonora, after his six-year-old niece Frances (Fanny) Leonora Hardey. In 1895, gold was discovered in the area by prospector Edward "Doodah" Sullivan at the Johannesburg lease just north of the current townsite. In the following two years a number of rich finds resulted in rapid development of the area. The Sons of Gwalia gold mine brought Leonora to the attention of the world. By 1897 a residential and business area had been established, and the town was gazetted as Leonora. Leonora had a single track passenger tramway linking the town and nearby Gwalia, from 1901 to 1921. Initially steam driven, the service was electric from November 1908, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peridotite
Peridotite ( ) is a dense, coarse-grained igneous rock consisting mostly of the silicate minerals olivine and pyroxene. Peridotite is ultramafic, as the rock contains less than 45% silica. It is high in magnesium (Mg2+), reflecting the high proportions of magnesium-rich olivine, with appreciable iron. Peridotite is derived from Earth's mantle, either as solid blocks and fragments, or as crystals accumulated from magmas that formed in the mantle. The compositions of peridotites from these layered igneous complexes vary widely, reflecting the relative proportions of pyroxenes, chromite, plagioclase, and amphibole. Peridotite is the dominant rock of the upper part of Earth's mantle. The compositions of peridotite nodules found in certain basalts are of special interest along with diamond pipes (kimberlite), because they provide samples of Earth's mantle brought up from depths ranging from about 30 km to 200 km or more. Some of the nodules preserve isotope ratios of osm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shire Of Laverton
The Shire of Laverton is a local government area in the Goldfields-Esperance region of Western Australia, about northeast of the city of Kalgoorlie and about east-northeast of the state capital, Perth. The Shire covers an area of , and its seat of government is the town of Laverton. History The Mount Margaret Road District was gazetted on 17 August 1906. It absorbed the Municipality of Mount Morgans on 28 February 1913. On 13 November 1925, it absorbed some land from neighbouring road districts, most notably Lawlers. It was renamed the Laverton Road District on 20 January 1950. It was made a shire on 1 July 1961 following the passage of the ''Local Government Act 1960'', which reformed all remaining road districts into shires. The residents of the Shire are represented by 7 Councillors.

Cobalt Mining Companies
Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments ( cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was for a long time thought to be due to the known metal bismuth. Miners had long used the name ''kobold ore'' (German for ''goblin ore'') for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the ''kobold''. Today, some cobalt is produced specifically from one o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nickel Mines In Western Australia
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. 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 and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ultramafic Rocks
Ultramafic rocks (also referred to as ultrabasic rocks, although the terms are not wholly equivalent) are igneous and meta-igneous rocks with a very low silica content (less than 45%), generally >18% MgO, high FeO, low potassium, and are composed of usually greater than 90% mafic minerals (dark colored, high magnesium and iron content). The Earth's mantle is composed of ultramafic rocks. Ultrabasic is a more inclusive term that includes igneous rocks with low silica content that may not be extremely enriched in Fe and Mg, such as carbonatites and ultrapotassic igneous rocks. Intrusive ultramafic rocks Intrusive ultramafic rocks are often found in large, layered ultramafic intrusions where differentiated rock types often occur in layers. Such cumulate rock types do not represent the chemistry of the magma from which they crystallized. The ultramafic intrusives include the dunites, peridotites and pyroxenites. Other rare varieties include troctolite which has a greater percentag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lateritic Nickel Ore Deposits
Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining of nickel. Genesis and types of nickel laterites Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite, peridotite and komatiite and their serpentinized derivatives, serpentinite which consist largely of the magnesium silicate serpentine and contains approx. 0.3% nickel. This initial nickel content is strongly enriched in the course of lateritization. Two kinds of lateritic nickel ore have to be distinguished: limonite types and silicate types. Limonite type laterites (or oxide type) are highly enriched in iron due to very strong leaching of magnesium and silica. They consist largely of goethite and contain 1-2% nickel incorporated in goethite. Absence of the limonite zone in the ore deposits is due to erosion. ...
