Tantalum as an investment can be a rather contentious topic among finance experts. Others call it a conflict resource and have linked the use of the metal to the war in the African country once known as Zaire. This war is sometimes called the African World War, and it involved 9 countries and about 20 separate armed groups.
Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue gray, lustrous transition metal that is highly corrosion resistant.

Tantalum ores are established mainly in Australia, Canada, Brazil, and central Africa, with some extra quantities originating in Southeast Asia and in China. There is also concern in journeying for this component in a variety of regions of the world, such as Canada, Egypt and Saudi Arabia.
Apr 11, 20130183;32;Tantalum Mineral Processing Tantalum ores are typically processed by careful milling of the ore to liberate the ne tantalum minerals. Following this initial stage, the milled ore is subjected to a series of physical or non chemical processes involving the use of gravity separation techniques. The gravity techniques utilize the earths natural gravitational (1G) force to separate the heavy tantalum (plus tin

Tantalite Ore Mineral Deposits Nigeria which is situated in the Western part of Africa has a significant and excellent deposit of tantalite, which is world class and is vastly deposited mostly in the northern parts of Nigeria, some of these deposits have been mined and some though discovered and in huge deposits have remained untouched.
Mining industry of Egypt. The chief minerals in terms of volume output were iron ore, phosphates, and salt. The quantities produced in 1986 were estimated at 2,048, 1,310, and 1,233 tons, respectively, compared with 2,139, 691, and 883 tons in 1981. In addition, minor amounts of asbestos (313 tons) and quartz (19 tons) were mined in 1986.
Apr 13, 20070183;32;Egypt is Africas leading producer of talc (84.7%) and gypsum (up to 42%), the second largest producer salt (20.4%), third largest producer of phosphate (7.7%) and vermiculite (3.4%), 4th for iron ore (2.8%), 5th largest for fluorspar and 7th largest for manganese.
Egypt, however, has medium grade reserves, of which the most important are at Al Bariyyah Oasis. The ore deposits in Morocco and Tunisia, which were once of considerable importance, have been severely depleted. Africas most significant iron reserves are to be found in western and Southern Africa.
Other, less common oxides of niobium and tantalum include tapiolite, ixiolite, and minerals of the perovskite group. Niobium and tantalum also substitute for major ions in some common oxide groups such as cassiterite, rutile, and ilmenite. Contents of niobium and tantalum in these minerals are rarely high enough to make them of economic interest.
The mineral group tantalite [(Fe, Mn)Ta 2 O 6 ] is the primary source of the chemical element tantalum. Tantalum, always together with the chemically similar niobium, occurs in the mineral groups tantalite, columbite and coltan (a mix of columbite and tantalite, though not recognised as a

COLTAN (Columbite Tantalite) is a dull metallic ore found in major quantities in the eastern areas of Congo. When refined, COLTAN becomes metallic Tantalum, a heat resistant powder that can hold a high electrical charge. Columbite ((Fe, Mn, Mg)(Nb, Ta) 2 O 6 Iron Manganese Magnesium Niobium Tantalum Oxide) is the most abundant niobium mineral and is used in alloys for improved strength.
Their production arises from the conversion of ores to iron, hot iron to steel, and from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel. These by products, especially in the past, were classified as waste and often stocked and or disposed in landfills, although they could be a valuable secondary raw material when recycled and properly reused.
Tantalite / Columbite tantalite ore groups are the major sources of metal tantalum which is a refractory metal . feldspar, mica, scheelite, cassiterite, uraninite and monazite. Also . America and sparingly Egypt and Saudi Arabia.
Tantalum ore has characteristically grades of about 0.03% Ta 2 O 5, generally as a co product of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hard rock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile.
Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non reactive and non irritating to body tissues.

Apr 24, 20170183;32;Tantalum comes from the processing and refining of tantalite. Tantalite is the common name for any mineral ore containing tantalum. Most tantalum mines are open pit; some are underground. The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum.
