Niobium was officially adopted as the name of the element in 1949, but the name columbium remains in current use in metallurgy in the United States. It was not until the early 20th century that niobium was first used commercially. Niobium is an important addition to high-strength low-alloy steels.
The Qaqqaarsuk deposit is a large niobium mine located in Qeqqata in southern Greenland. Qaqqaarsuk represents one of the largest niobium reserves in Greenland having estimated reserves of 3.5 million tonnes of ore grading 0.5% niobium .
The main source of niobium until now has been from the ore mineral columbite that is extracted widely in Canada, Brazil, Australia and Nigeria, with China obtaining nearly 95 per cent of the ...
In 2019, Brazil's figures were as follows: it was the world's largest producer of niobium (88.9 thousand tons); [2] the 2nd largest world producer of tantalum (430 tons); [3] the 2nd largest world producer of iron ore (405 million tons); [4] the 4th largest world producer of manganese (1.74 million tons); [5] the 4th largest world producer of bauxite (34 million tons); [6] the 4th largest ...
Diagram as published by McKelvey in 1973 [1] Diagram as published by McKelvey in 1976 [2] A McKelvey diagram or McKelvey box is a visual representation used to describe a natural resource such as a mineral or fossil fuel, based on the geologic certainty of its presence and its economic potential for recovery. The diagram is used to estimate the ...
Columbite, also called niobite, niobite-tantalite and columbate, with a general chemical formula of (Fe II,Mn II)Nb 2 O 6, is a black mineral group that is an ore of niobium. It has a submetallic luster, a high density, and is a niobate of iron and manganese. Niobite has many applications in areospace, construction and the medical industry.
