Potentiality of Rare Earth Elements in Brazil ScienceDirect

Jan 01, 2016· Brazilian rare earth element (REE) deposits are associated with carbonatitealkaline complexes, granitic intrusions, and marine placers. The Araxá project is an example of an REE deposit associated with alkaline carbonatite rocks; it has an estimated resource higher than 40 million tons (Mt) of 3.0% REE 2 O 3 as a byproduct of niobium tailings and is the most advanced REE project in Brazil.

Mineralogical and physical studies of lowgrade tantalum

Sep 01, 2021· The gravity concentration done on the oresamples resulted in concentrate with compositions of 66.14%SnO 2, 7.66%Ta 2 O 5 and 7.70% Nb 2 O 5. This study therefore provides the baseline data for the selection and designing the appropriate techniques to effectively harness the tantalumtin minerals from the sampled areas.

Transporting NORM (Naturally Occurring Radioactive

For columbite, tantalite, tin slag and other Ta/Nb raw materials, the extraction of the valuable niobium and tantalum content and removal of the Th/U to waste, requires specialised digestion in e.g. hot HF/H 2 SO 4 acid which is conducted by chemical processors located far from the minesites. Transport is therefore required, almost always
