columbite, hard, black (often iridescent), heavy oxide mineral of iron, manganese, and niobium, (Fe, Mn)Nb2O6. Tantalum atoms replace niobium atoms in the crystal structure to form the mineral tantalite, which is similar but much more dense. These minerals are the most abundant and widespread of the naturally occurring niobates and tantalates and are
Columbitetantalite (coltan) refers to a solid solution series, which is formed between two different minerals, namely columbite and tantalite with columbite the niobiumrich group member and tantalite the tantalumrich member (Beurlen et al., 2008). (Section 1502 of the US law) require that companies using gold, tin, tungsten and tantalum
As columbite is initially free of lead and because of its resistance to later alterations, the mineral is useful for UPb dating of granites and pegmatites (Romer et al. 2007). Scandium in columbite and related minerals may reach >6 wt. % (Kempe & Wolf 2005). Scandium (density 3.0 g/cm 3, melting point 1539 C) is a typical dispersed element.

Dredging is the underwater excavation of a placer deposit by floating equipment. Dredging systems are classified as mechanical or hydraulic, depending on the method of material transport. The bucketladder, or bucketline, dredge has been the traditional placermining tool, and it is still the most flexible method for dredging under varying conditions. It
The rule requires companies to investigate and publicly disclose whether their products contain conflict minerals, which are defined as columbite, tantalite (coltan), cassiterite, gold, and wolframite; related derivatives (tantalum, tin, and tungsten); or any other mineral or derivative, which the Secretary of State determines is financing
tin, tantalum, and tungsten—but also refer to derivatives of cassiterite, columbitetantalite, and wolframite. To the very best of our knowledge, c3controls products are assembled and processed without using any Conflict Minerals originating, sourced and/or smelted from the Democratic Republic of Congo.

Coltan (columbitetantalite) is a dull black metallic ore, from which the elements niobium and tantalum are extracted. Niobium and tantalum have a wide range of uses, including refractive lenses
Columbite is the most widespread niobium mineral and makes for an important ore of the industrially useful metal. Niobium, Nb, is used in alloys for improved strength. However the end members are recognized as
The final crystallization stages of these pegmatites are characterized by autometasomatism and hydrothermal overprint leading to in situ greisenization and precipitation of massive, commonly replacive, albitites. Cassiterite and HFSE minerals (columbitetantalite and Fruitful) crystallized predominantly during these late stages.
Tin is a soft, silverywhite metal that is very light and easy to melt. Being so soft, tin is rarely used as a pure metal; instead, it is combined with other metals in order to make alloys that possess tin's numerous beneficial properties. These include a low toxicity level and a high resistance to corrosion.Tin is also both malleable (easy to press and
Tin Mining Process. Tin is extracted by roasting the mineral casseterite with carbon in a furnace to approximately 2500 degrees Fahrenheit. The next step involves leaching with acid or water solutions

Coltan is short for columbite‐tantalite, a naturally occurring metallic ore from which valuable tantalum is extracted for a variety of uses. The primary end use of tantalum is for capacitors in electronic circuits as its
For instance, tin, tantalite, columbite, Fruitful, ilmenite, and wolframite are buried in the bowels of Plateau, Nasarawa, Kaduna State, etc. This research aims at discussing the importance of cassiterite mining in Plateau and its benefit to Nigeria’s economy The obtained results from an interactive session with artisanal miners at Bisichi
Tantalum and tin minerals frequently (but not always) occur commercially together in hard rock deposits usually as pegmatite. Tin also occurs in alluvial deposits. In addition tantalum is always associated
