Niobium Mineralisation in AustraliaJORC Ore ReservesIdentified ResourcesProductionWorld RankingIndustry DevelopmentsCitationWorld niobium and tantalum resources are poorly reported. Central Africa is known to host major resources but dependable resource estimates are rarely available. According to world estimates published by the USGS16, and supplemented with Australian figures, Australias niobium resources are minor, accounting for about 4 of global niobium resources in 2018. This places Australia third in the world for reliably reported economic resources behind Brazil, Canada and followed by the USA. The USG

Niobium Minerals and Production TIC

Columbite, the niobium rich homologue of the mineral columbotantalite, occurs in Brazil, Nigeria, and other countries in central Africa. Unlike pyrochlore, columbite is not processed at or near the minesite into niobium metal products, but is transported to the same processing industries which receive tantalum materials. There, the columbite is treated in the same manner as tantalite and ...
