Titanium In Africa
Titanium mining in Africa has been beset by environmental problems due to the polluting nature of processing rutile, a principal titanium ore. Titanium production in Africa includes the following principal countries and companies. Kenya * Base Titanium ''of Australia'' * Tiomin Resources ''of Canada'' ** Tiomin Kenya **''Location:'' Eldoret; Kwale Mozambique * Kenmare Resources ''of Ireland'' ** Kenmare Moma Mining ** Kenmare Moma Processing ** Moma Mineral Sands Project **''Location'' Nampula Province **Involves investment from African Development Bank (ADB); European Investment Bank (BEI), the Development Bank of Southern Africa (DBSA); and the German Development Bank (KfW). **Principally mining Ilmenite Sierra Leone *Sierra Rutile ''of Ohio; since 1967'' **''Location:''Bonthe/Port Loko District; Tonkoli District ** Branch Energy ''UK'' ** Diamond Works **Executive Outcomes ''RSA'' **Sandline International * Sierra Leone Ore and Metal Company ''since 1963'' **''Location: ...

Titanium
Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and catalysts; and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Development Bank
The African Development Bank Group (AfDB) or (BAD) is a multilateral development finance institution headquartered in Abidjan, Ivory Coast, since September 2014. The AfDB is a financial provider to African governments and private companies investing in the regional member countries (RMC). The AfDB was founded in 1964 by the Organisation of African Unity, which is the predecessor of the African Union. The AfDB comprises three entities: The African Development Bank, the African Development Fund and the Nigeria Trust Fund. Mission The AfDB's mission is to fight poverty and improve living conditions on the continent through promoting the investment of public and private capital in projects and programs that are likely to contribute to the economic and social development of the region. History Following the end of the colonial period in Africa, a growing desire for more unity within the continent led to the establishment of two draft charters, one for the establishment of t ...

Diamond Works
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. Diamond also has a very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Branch Energy
A branch, sometimes called a ramus in botany Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek w ..., is a woody structural member connected to the central trunk (botany), trunk of a tree (or sometimes a shrub). Large branches are known as boughs and small branches are known as twigs. The term ''twig'' usually refers to a wikt:terminus, terminus, while ''bough'' refers only to branches coming directly from the trunk. Due to a broad range of species of trees, branches and twigs can be found in many different shapes and sizes. While branches can be nearly vertical and horizontal, horizontal, vertical, or diagonal, the majority of trees have upwardly diagonal branches. A number of mathematical properties are associated with tree branchings; they are natural examples of fractal pattern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
