They are end-members of a solid solution series. Columbite is niobium-rich, while tantalite is tantalum-rich. The intermediate minerals are called columbite-tantalite or 'coltan'.
Not exactly. 'Coltan' is a colloquial/mining term for a columbite-tantalite ore mixture. Columbite specifically refers to the niobium-dominant mineral.
Columbite is most commonly found in granitic pegmatites, which are coarse-grained igneous rocks.
It is a major source of niobium, which is a critical metal for producing high-strength, low-alloy steels and superalloys used in pipelines, automotive frames, and jet engines.
