This chapter discusses the concentration of feldspars with heavy liquids—a technique essentially similar to the separation of heavy minerals from a sample. The chapter also focuses on the aspects of flotation, a method based on the composition of a feldspar surface. Feldspars can be separated from sediment or a soil by different methods.

Flotation was conducted in a Denver D-12 laboratory flotation machine equipped with a 3.5 dm 3 Minnovex cell. The impeller speed and air flow rate were set at 1400 rpm and 8 dm 3 /min respectively. A flotation test sample of 1.2 kg was mixed with 2.8 dm 3 tap water and conditioned at 1400 rpm to give 30% solids by weight. Dodecylamine …

The first method is to flotation mica in acidic medium with amine collector, the pH value is controlled below 3.5, and the upper limit of the flotation particle size is 1.2mm. And desliming is ...

The common feldspar beneficiation flow mainly includes the following four types: High-quality feldspar produced in pegmatite: hand selection – crushing – wet grinding – classifying. Feldspar in weathered granite: washing – crushing – grinding – classification – flotation (removal of iron and mica or separation of feldspar and quartz).

After performing the froth-flotation separation on the collected mica mineral sample using the optimal pH condition (i.e., pH 3.5) with the same concentrations of the collector (Armac-T = 1000 mg/kg-soil), and the frother (AF65 = 50 mg/kg-soil) and the same flow rate (80 L/h) and injection time (5 min) of the compressed air, the particle size ...
