What is the final product of columbite?

The final products derived from columbite typically include niobium and tantalum. Columbite, generally found together with tantalite as coltan, is processed to extract these valuable metals. Niobium is used primarily in the production of high-grade structural steel and in superconducting materials, while tantalum is used in electronics, particularly in capacitors and high-power resistors due to its ability to hold and release electrical charges efficiently.
