The Motzfeldt mine is a large niobium mine located in southern Greenland in Kujalleq. Motzfeldt represents one of the largest niobium reserves in Greenland having estimated reserves of 130 million tonnes of ore grading 1% niobium and 0.04% tantalum.
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 .
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 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 ...
