niobium tantalum purer in angola

Tantalum was discovered in Sweden in 1802 by Anders Ekeberg One year earlier Charles Hatchett had discovered columbium now niobium In 1809 the English chemist William Hyde Wollaston compared its oxide columbite with a density of 5918 gcm3 to that of tantalum with a density of 7935 gcm3...
