Mine waste from carbonatite deposits as potential rare ...

Mining waste from carbonatite deposit as potential source of rare earth elements • The abundance of REE-bearing- and REE-minerals confirm their economic potential. • REE extraction from East tailing might produce up to 5.65 kg/t. • Re-mining tailings reduces the waste of resources and their environmental impact.

Primary and secondary niobium mineral deposits

This work reviews the character and origin of primary and supergene economic deposits of niobium associated with carbonatites. The Brazilian supergene deposits account for about 92% of the total worldwide production of Nb, with the primary St. Honoré carbonatite and other sources accounting for only for 7 and 1%, respectively.

Phoscorites and Carbonatites from Mantle to Mine: the

2004-7-1  Phoscorites are dark, often very handsome, sometimes economically valuable, magnetite-apatite-silicate rocks, almost always associated with carbonatite. They are key to understanding the longstanding question of how carbonate and carbonate-bearing magmas rise to the crust and the Earths surface. Despite this, they have been given little attention; a search on geological literature databases ...
