Feldspar flotation as a quartzpurification method in
Our flotation cell is built of borosilicate glass holds up to 90 g of sample and achieves quartz and feldspar separation in ≤2 h • The procedure uses air bubbles to which the feldspars attach 02 HF to reduce the surface energy of quartz dodecylamine solution as a feldspar collector and operates at a pH range of 24–27 at room temperature
