Study on Flotation Mechanism of Separation of Potassium Feldspar from Quartz with Anion and Cation Mixed Collector

Abstract:

Potassium feldspar and quartz are all silicate minerals with frame structure,and have the similar crystal structure and physicochemical properties. Therefore, flotation has become the main method to separate potassium feldspar from quartz. The separation of potassium feldspar from quartz with anion and cation mixed collector was studied in the paper. The sodium oleate and sodium dodecyl benzene sulfonate were respectively used as collector agents in potassium feldspar and quartz single mineral flotation tests. The analysis of the variation of the surface properties of potash feldspar and quartz after using the collectors was conducted with infrared spectra and electrokinetic potential, followed by the mechanism of separation of potassium feldspar from quartz with anion and cation mixed collector.
