Quartz Flotation Concentrate

The Effect of Quartz on the Flotation of Fine Wolframite ...

Quartz is the major gangue mineral associated with fine wolframite in the flotation concentrate. Si and O atoms occupy the entirety of the surface of quartz, but those atoms are not active sites for the adsorption of anionic surfactants. Additionally, quartz is a naturally hydrophilic oxide. It seems inconceivable that a relatively high content of quartz

Flotation of quartz from quartz-feldspar mixtures by the ...

01/11/2016  Flotation experiments performed on a quartz-feldspar mixture demonstrate that quartz can be floated selectively from feldspars in diluted solutions of hydrofluoric acid (HF) simply by the aid of a frother. High grades and good recoveries were obtained for both quartz and feldspars. A feldspar concentrate of 99.9% at a recovery of 95.6% was produced. No further cleaning of the quartz ...
