Review of flotation of feldspar: Mineral Processing and ...

2018-6-8 · Abstract. This paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite) as well as the separation of the individual feldspar minerals themselves.

Flotation of quartz from quartz-feldspar mixtures by

2021-1-9 · Abstract 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.

2019-10-1 · The selective fluorine activation of the feldspar surface by HF or similar (i.e. NaF + acid) is generally understood to be the reason for the preferential amine adsorption onto feldspar, as the amine ion cannot sufficiently adsorb on the feldspar surface by itself to promote the flotation of feldspar in the acidic medium (Shimoiizaka et al., 1976).
