froth floatation separation quartz from feldspar

Potassium feldspar and quartz are all silicate minerals with frame structureand 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 quartz samples contained small amounts of feldspars 3 10 indicating that neither density separation nor magnetic separation can fully remove all feldspars and that HF etching is essential SEMEDS mapping also showed that the alkali feldspar extracts contained some quartz grains 5 Roughly15 Narich grains were observed within
