Tantalite: The mineral columbite-tantalite information and ...

Tantalite forms a solid solution series with Columbite known as the Columbite-Tantalite series. Tantalite is the tantalum-rich member, and Columbite is the niobium-rich member. Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum.Tantalite forms a solid solution series with Columbite known as the Columbite-Tantalite series.
