Tantalum and niobium are rare metals primarily sourced from minerals such as columbite and tantalite. These minerals are often found in igneous rocks and are important for their high melting points and resistance to corrosion. Tantalum is widely used in electronics, particularly in capacitors, while niobium is essential in steel production and superconducting materials. Both metals are critical for various industrial applications, including aerospace and medical devices. The extraction of tantalum and niobium involves complex processes, often requiring advanced technology to separate them from other minerals. Their scarcity and demand make them valuable resources in the global market.
