About Tantalite
A tantalite é um mineral de minério primário de tântalo, formando cristais prismáticos negros a castanho-avermelhados ou castanho-negros com um lustre submetálico a resinoso. Ocorre em pegmatitos graníticos em todo o mundo, com importantes depósitos na Austrália, Brasil, Congo e Ruanda. Embora lapidada ocasionalmente para colecionadores, o seu principal valor é como minério de tântalo, metal essencial em condensadores eletrônicos e superligas.
