Sierra Rutile
Sierra Rutile Limited (Titanium Resources Group Ltd. until 2011) is a mining company with headquarters based in Freetown, Sierra Leone. The company currently has operating mines for Rutile, ilmenite, zircon, and titanium dioxide minerals in South and Northwest Sierra Leone, specifically in the Moyamba and Bonthe Districts. Australian-based Iluka Resources Limited acquired the company in December 2016 and subsequently installed new and currently acting CEO Rob Hattingh. History Sierra Rutile Limited was officially founded in December 1971 by Nord Resources and Armco Steel. However, mining operations began in the area in 1967, which is recognized by some as the inception of the firm. In 1993, the company had the highest rutile (a titanium mineral) production in the world; however, this milestone was short-lived as the Sierra Leonean Civil War disrupted mining progress. * In 1995 the company abandoned their operation because of the Sierra Leone Civil War. * In January 2005, the ...

Iluka Resources
Iluka Resources is an Australian-based resources company, specialising in mineral sands exploration, project development, operations and marketing.

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

Ticker Symbol
A ticker symbol or stock symbol is an abbreviation used to uniquely identify publicly traded shares of a particular stock on a particular stock market. In short, ticker symbols are arrangements of symbols or characters (generally Latin letters or digits) representing specific assets or securities listed on a stock exchange or traded publicly. A stock symbol may consist of letters, numbers, or a combination of both. "Ticker symbol" refers to the symbols that were printed on the ticker tape of a ticker tape machine. Interpreting the symbol Stock symbols are unique identifiers assigned to each security traded on a particular market. A stock symbol can consist of letters, numbers, or a combination of both, and is a way to uniquely identify that stock. The symbols were kept as short as possible to reduce the number of characters that had to be printed on the ticker tape, and to make it easy to recognize by traders and investors. The allocation of symbols and formatting conventions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alternative Investment Market
AIM (formerly the Alternative Investment Market) is a sub-market of the London Stock Exchange that was launched on 19 June 1995 as a replacement to the previous Unlisted Securities Market (USM) that had been in operation since 1980. It allows companies that are smaller, less-developed, or want/need a more flexible approach to governance to float shares with a more flexible regulatory system than is applicable on the main market. At launch, AIM comprised only 10 companies valued collectively at £82.2 million. As at May 2021, 821 companies comprise the sub-market, with an average market cap of £80 million per listing. AIM has also started to become an international exchange, often due to its low regulatory burden, especially in relation to the US Sarbanes–Oxley Act (though only a quarter of AIM-listed companies would qualify to be listed on a US stock exchange even prior to passage of the Sarbanes–Oxley Act). By December 2005, over 270 foreign companies had been admitted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dredge
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release human-sourced toxins captured in the sediment.

Gondwana Investments
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pangae ...

Sierra Leone Civil War
The Sierra Leone Civil War (1991–2002), or the Sierra Leonean Civil War, was a civil war in Sierra Leone that began on 23 March 1991 when the Revolutionary United Front (RUF), with support from the special forces of Liberia, Liberian dictator Charles Taylor (Liberian politician), Charles Taylor's National Patriotic Front of Liberia (NPFL), intervened in Sierra Leone in an attempt to overthrow the Joseph Momoh government. The resulting civil war lasted 11 years, enveloped the country, and left over 50,000 dead.Gberie, p. 6 During the first year of the war, the RUF took control of large swathes of territory in eastern and southern Sierra Leone, which were rich in alluvial diamonds. The government's ineffective response to the RUF, and the disruption in government diamond production, precipitated a military ''coup d'état'' in April 1992 by the National Provisional Ruling Council (NPRC).Gberie, p. 103 By the end of 1993, the Republic of Sierra Leone Armed Forces, Sierra Leone Ar ...

Rutile
Rutile is an oxide mineral composed of titanium dioxide (TiO2), the most common natural form of TiO2. Rarer Polymorphism (materials science), polymorphs of TiO2 are known, including anatase, akaogiite, and brookite. Rutile has one of the highest refractive index, refractive indices at visible wavelengths of any known crystal and also exhibits a particularly large birefringence and high dispersion (optics), dispersion. Owing to these properties, it is useful for the manufacture of certain optical elements, especially Polarization (waves), polarization optics, for longer light, visible and infrared, infrared wavelengths up to about 4.5 micrometres. Natural rutile may contain up to 10% iron and significant amounts of niobium and tantalum. Rutile derives its name from the Latin ('red'), in reference to the deep red color observed in some specimens when viewed by transmitted light. Rutile was first described in 1803 by Abraham Gottlob Werner. Occurrence Rutile is a common accessory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
