What is another word for coltan?
Pronunciation: [kˈə͡ʊltən] (IPA) 
Coltan, also known as columbite-tantalite, is a metallic ore that is used primarily in the manufacturing of electronic devices. The term is often used interchangeably with tantalite, which is one of the minerals that comprise the ore. Other synonyms for coltan include niobite-tantalite, ferrotantalite, and yttrocolumbite. Coltan has particularly gained attention in the last few years due to ethical concerns surrounding its mining, such as child labor and exploitation of workers. As such, companies are increasingly turning to alternative mineral sources, such as recycling or alternative metals, to reduce their reliance on coltan. Despite its controversial reputation, coltan remains an important component for electronics manufacturing.
