Nov 01, 2016· The role of HF in the flotation of feldspar has been studied by several authors in the past, and several possible mechanisms have been proposed (Dean and Ambrose, 1944, Graham and Horning, 1947, Buckenham and Rogers, 1954, Smith and Smolik, 1965, Perry et al., 1983). In conclusion, all reported studies support the suggestion that the feldspar surface could become more negative when treated with HF

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.

Review of flotation of feldspar: Mineral Processing and

Jul 18, 2013· Potassium feldspar can be floated from sodium feldspar in a sodium chloride solution with an amine collector at neutral or acidic pH values. To overcome environmental issues when fluoride ions are used to activate the feldspar in the third flotation stage, fluoride free flotation conditions that utilise a combination of anionic and cationic collectors have been developed.

The second method is fluorine-free flotation, which could solve the problem caused by environmental pollution of HF flotation. Applying aliphatic amines and petroleum sulfonate mixing collector in strong acidic environment using H 2 SO 4 or HCl as pH regulator, selective flotation separation of feldspar from quartz [11,12,13] could be achieved. However, the effectiveness of this separation method is worse

Understanding the flotation separation of Na and K

Dec 01, 2018· Flotation is the only technique that enables the selective separation of Na and K feldspar minerals from each other. In this study, the flotation separation of Na-feldspar (albite) and K-feldspar (microcline) minerals were investigated in the presence of K + ion as counter ion. In order to identify the role of K + ions on the selective separation of feldspar minerals, solubility, adsorption
