Ore, Tantalum, Niobium, Coltan, Columbite, Tantalite, Niobium Ore, Tantalite Ore.

Niobium is a gray and ductile metal, very similar to tantalum. It’s extracted from an ore called coltan (columbite and tantalite composed). The columbite – compound niobium oxide, iron and manganese [(Fe, Mn) Nb2O6] 98% of its reserves are in the state of Amazonas and Roraima. The Oreization of Ta an Nb economically most valuable and important are the tantalite – compound niobium oxide, iron and manganese [(Fe, Mn) Nb2O6]-. And if it’s the opposite it’s called Tantalite. The more niobium the mineral contains and the less tantalum, it is called Columbite-Tantalite or Ferrocolumbite-Tantalite, and the less niobium and the more tantalum it is called Tantalite. Columbite is common in nature forming elements are combined and Ores predominate over each other, as in this case. Columbite and tantalite, together with other Ores of tantalum and niobium carriers, they’re known informally by the abbreviation “coltan”; but if you want to accurately and appropriately refer to on this wealth, which has Venezuela, Brazil and Colombia, it’s necessary to start talking particularly of tantalum and niobium Oreization of these basic elements. Tantalum and niobium are refractory metals. They have a high melting point and withstand exceptionally high temperatures, 3017° C and 2468° C respectively. The heat resistence of Ta is twice the iron and is exceeded only by tungsten and rhenium; accordingly, the Ta and Nb have the potential to be used in high temperature resistant applications. Even, tantalum carbide (TaC) supports 3880°C and further has hardness similar to diamond. Nb and Ta are well known and no exists any mystery about them; appear bright gray color tending to turn blue when comes into contact with air; both belong to the goup of transition metals, have high density and weight, good ductility, are resistant to corrosion and superb thermal and electrical conductors. Thanks to its exceptional propierties, are currently used in the manufacture of high-tech components and super-strong metallurgical alloys.

Ore, Tantalum, Niobium, Coltan, Columbite, Tantalite.

It’s a blue- gray, shiny, heavy, ductile, hard and a good conductor of electricity and heat dark metal. Tantalum is extracted from an ore called coltan (columbite and tantalite composed). Tantalite has properties that have contributed to the progress of the electronic industry: it has high conductivity, has refractive power (high temperature resistant), temporarily stores electrical charge and releases it when needed and also resists corrosion. The Oreization of Ta and Nb economically most valuable and important are the tantalite – compound of tantalum oxide, iron and manganese [(Fe, Mn Ta2O6] – and columbite – compound niobium oxide, iron and manganese [(Fe, Mn) Nb2O6]. For these reasons coltan is essential for the production and miniaturization of capacitors for mobile phones, computers, monitors, GPS systems, satellite guided weapons or material.

Mineral, Hierro, ferro, iron ore, Fe2O3.

Iron is a metal amply used by industries. It’s found in nature as a Ore. The iron ore is present in admixture with impurities and soil (ground) deposits. After going through a process of cleansing and purifying iron ore is taken to high temperature furnaces in the steel. In this process it is transformed into pig iron, with a hard but fragile consistency. Cast iron can go through other special procedures to be converted into steel (alloy of iron and carbon). Steel has the advantage of being flexible, so it is widely used in automobiles, household appliances, etc. Chemical Specifications:
