There is no state in Nigeria that is lacking in one resources or another. We are determined to explore and exploit these resources to the maximum benefits of our people. Kano, for example, has huge agricultural potentials and important mineral resources underneath its ground like gold, silver, nickel, tin ore and columbite.
Africa is blessed with a lot of solid minerals including Gold, Iron Ore, Tin, Columbite, and Diamonds among several others. You can start a business that explores and extracts these minerals for sale. Businesses like this get a lot of foreign investment. 29. Virtual Reality Centers.
Pyrolusite is a mineral consisting essentially of manganese dioxide (Mn O 2) and is important as an ore of manganese. It is a black, amorphous appearing mineral, often with a granular, fibrous, or columnar structure, sometimes forming reniform crusts. It has a metallic luster, a black or bluish-black streak, and readily soils the fingers.The specific gravity is about 4.8.
The mineral group tantalite [(Fe, Mn)Ta 2 O 6] is the primary source of the chemical element tantalum, a corrosion (heat and acid) resistant metal.It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides. However, tantalite has a much greater specific gravity than …
Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may …
The major mineral resources found in Nigeria include tin, coal and columbite. Other mineral resources include gold, tantalite bitumen, lignite and cotton among others.
Rubidium is the first element placed in period 5. It is an alkali metal, the most reactive group in the periodic table, having properties and similarities with both other alkali metals and other period 5 elements.For example, rubidium has 5 electron shells, a property found in all other period 5 elements, whereas its electron configuration's ending is similar to all other alkali metals: s 1.
Columbite, also called niobite, niobite-tantalite and columbate [(Fe, Mn)Nb 2 O 6], is a black mineral group that is an ore of niobium.It has a submetallic luster and a high density and is a niobate of iron and manganese.This mineral group was first found in Haddam, Connecticut, in the United States.It forms a series with the tantalum-dominant analogue ferrotantalite and one with …

Sperrylite is a platinum arsenide mineral with the chemical formula PtAs 2 and is an opaque metallic tin white mineral which crystallizes in the isometric system with the pyrite group structure. It forms cubic, octahedral or pyritohedral crystals in addition to massive and reniform habits. It has a Mohs hardness of 6 - 7 and a very high specific gravity of 10.6.
Scheelite is a calcium tungstate mineral with the chemical formula Ca W O 4.It is an important ore of tungsten (wolfram). Scheelite is originally named after Swedish chemist K. Scheele (1742-1786). Well-formed crystals are sought by collectors and are occasionally fashioned into gemstones when suitably free of flaws. Scheelite has been synthesized using the Czochralski …
This ore is so rich in limonite (generally grading 47% to 59% iron, 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to low-grade iron ore. As such, certain steel smelters in China have developed a process for blending nickel limonite ore with conventional iron ore to produce stainless steel feed products.
