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,Developing Effective Separation of Feldspar and Quartz,,The micro-flotation tests revealed that there was little difference in the flotation of feldspar and quartz at pH 2, using H2SO4 as pH regulator. After HF pretreatment, the floatability of feldspar significantly increased while the floatability of quartz showed no change.Flotation of quartz from quartz-feldspar mixtures by the,,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.

18-07-2013· In the first flotation stage, mica is removed with an amine collector. In the second stage, titanium and iron oxide minerals, such as ilmenite and magnetite, are removed using an anionic collector. In the third stage, feldspar is activated with fluoride ions and floated with an amine. The residual product is usually high grade quartz.Differential Flotation of Some Egyptian Feldspars for,,amine hydrochloride collectors were used for the flotation of feldspars in presence of HF or a mixture of HF and NaCl. The C 10-12 amine gave the best flotation results [7] [8]. The feldspar was activated whereas the quartz was depressed by conditioning with HF.
