niobium tantalum flotation

Handbook of Flotation Reagents: Chemistry, Theory and ...

Beneficiation of this ore using cationic flotation, normally employed for flotation of niobium, was not applicable for this particular ore, since most of the mica and feldspar floated with the niobium and tantalum. The selectivity between Ta/Nb and gangue minerals using a cationic collector was very poor.

Niobium - an overview | ScienceDirect Topics

Tantalum and niobium in arc magmas are depleted relative to REEs, so that Nb/La and Ta/La are lower than in the primitive mantle and in MORBs. Depletion of primitive arc magmas in tantalum and niobium relative to lanthanum and thorium (Figure 14) is ubiquitous (a few niobium-enriched lavas—e.g., Kepezhinskas et al., 1997 —form a distinct ...
