Coltan Grade 2 – كولتان درجه تانيه

Coltan Tantalum Mineral


Coltan, short for columbite-tantalites, is a dull black metallic ore from which the elements niobium (formerly known as columbium) and tantalum are extracted. The tantalum-dominant mineral in coltan is tantalite. In appearance, coltan is a black, tar-like mineral. It is found in a variety of environments such as pegmatites (igneous rock formations), but it is most commonly associated with granite and granitic pegmatites. The ores are extracted as by-products of tin and tungsten mining in some cases. Coltan is significant because tantalum, derived from it, is used in the manufacture of tantalum capacitors, which are critical components in many electronic devices. Tantalum capacitors are valued for their high capacitance, durability, and resistance to thermal and chemical degradation. These properties make them crucial in the production of cell phones, laptops, and other high-tech electronics.Coltan ore producer location from Congo.
