Pegmatite-containing niobium ores can be relatively complex and may contain biotite, enargite, albite, feldspar, and ziron as the main gangue minerals. Some pegmatite ores (Araxa, Brazil) have a simple gangue composition, consisting mainly of quartz. Flotation of pyrochlore using sodium alkyl sulphate is dependent on flotation pH.

The recovery of wollastonite was closer to that of diopside than that of quartz. It was concluded that wollastonite is less floatable with DDA in batch flotation tests than it was in microflotation tests which is probably related to the solution chemistry and/or the effect of particle shape in a highly turbulent flotation
